All YOU simply need is the right treatment.
King Brand Healthcare Products is the manufacturer of FDA-registered Class II medical devices for the treatment of soft tissue injuries. This guide covers what a rotator cuff injury is, why it happens, and how to treat it correctly.
The rotator cuff is a group of four muscles and their tendons that stabilize the shoulder joint and enable rotational arm movement. The four muscles are the supraspinatus, infraspinatus, teres minor, and subscapularis. These tendons form a "cuff" that holds the ball of the shoulder in its socket.
Rotator cuff injuries range from inflammation (tendonitis) to partial and complete tears. The most commonly injured tendon is the supraspinatus, which passes through a narrow space beneath the shoulder bone. When this space narrows due to inflammation or bone spurs, the tendon gets pinched -- a condition called shoulder impingement.
Rotator cuff tendons have a naturally poor blood supply, which is why they heal slowly and why injuries often become chronic. Studies show that tears increase with age and many are asymptomatic. The absence of pain does not mean the tendon is healthy, and the presence of pain means the tendon needs attention.
The most common symptoms:
A sharp, sudden pain accompanied by a popping sensation may indicate an acute tear. If you suspect a tear, seek medical evaluation. However, most rotator cuff injuries are chronic overuse conditions that can be treated conservatively.
Understanding your specific cause matters for full recovery. See Rotator Cuff Information for more detail.
The King Brand treatment protocol for rotator cuff injury uses three FDA-registered medical devices working together, each addressing a different part of the recovery problem:
The order matters. Cold first, because treating an inflamed injury with anything else is premature. Support throughout, because every re-injury resets the healing clock. Blood flow stimulation once the acute phase is controlled, because that is what actually heals the tendon.
For the full protocol details, see Rotator Cuff Treatment.
BFST® + ColdCure® + KB Tape™
BFST® for Rapid HealingColdCure® for Pain & SwellingKB Tape™ to Prevent Re-Injury
Combination Therapy means using ColdCure®, KB Support Tape™ and BFST® in combination by alternating treatments. Combination Therapy is much more effective than using just one product or the other. This is because you're getting the pain and swelling relief of ColdCure®, the healing benefits of BFST®, and the protection and re-injury prevention of KB Support Tape™, resulting in the absolute best treatment for your Rotator Cuff Injury.
ColdCure is a registered Class II medical device that delivers cold compression therapy for pain, swelling, and inflammation associated with soft tissue injuries.
Cold and compression applied to an injury that is swollen, inflamed, or painful is extremely effective. ColdCure treatments are beneficial following injury until the pain, swelling, and inflammation are gone, and any time you experience symptomatic flare-ups.
Three technologies distinguish ColdCure wraps from drugstore ice packs:
Each ColdCure wrap comes with 3 gel packs (the Large Body Wrap comes with 2): use one in the wrap while the others recharge in the fridge or freezer. Switch to a freshly charged pack when the cold diminishes, typically after 20 minutes.
KB Support Tape is a registered Class I medical device with two functions: ongoing compression to control swelling, and support to protect against re-injury.
The support function is the important one for rotator cuff injury recovery. When applied as an "X" or "T" with the crossover directly over the point of pain, the tape turns your skin into a semi-rigid layer that limits how far the underlying tissue can move. King Brand calls this "armor for your injury."
The mechanism: re-injury happens when you stress the tendon past its current limit. Tape does not remove the load, but it reduces how far "too far" is. Say your tendon can handle a 20-pound load but not 25. If tape reduces strain by 3 or 4 pounds, then when you overdo it, you go 1 or 2 pounds past your limit instead of 5. Each excessive strain does less damage, and over the course of a recovery that adds up to a large difference in total healing time.
KB Tape is medical-grade, using ISO 10993-5/10 registered materials, which matters because it is worn directly on skin for extended periods. It stays in place 1 to 3 days and can be worn in the shower.
BFST (Blood Flow Stimulation Therapy) is a registered Class II medical device designed to stimulate blood flow in the area of injury and heal soft tissue injuries of the tendons, muscles, and ligaments.
The rotator cuff injury recovery dilemma: rest avoids re-injury but restricts circulation; activity improves circulation but risks re-injury. BFST resolves this. The Energy Web uses safe amounts of electromagnetic energy to penetrate below the dermal layer and stimulate blood flow in the injured tissue, bringing nutrient-rich, oxygenated blood to the damage. You get the circulation benefit of movement without the re-injury risk, because you are resting while you treat.
Treatment specifics:
BFST is not a heating pad. Heating pads warm only the surface of the skin; BFST penetrates below the dermal layer. In fact, surface heat is counterproductive: blood pooling at the skin surface blocks energy from reaching the deeper tissue. Less surface heat means more energy delivered to the injury.
Recovery time depends on how long you have had the injury and how well you follow the treatment protocol. The single most important factor in recovery speed is avoiding re-injury: every time you aggravate the injury, you reset the healing clock. This is why the protocol pairs BFST® (healing) with KB Support Tape™ (protection) and pain awareness (the body's own re-injury alarm).
Recovery time depends on whether the injury is tendonitis, a partial tear, or a complete tear, and how long you have had it. Acute tendonitis treated properly may improve within 2-3 weeks of regular BFST treatments. Partial tears take longer, typically 6-12 weeks. Chronic conditions take longer still.

There is a lot of bad advice about rotator cuff injury on the internet. These are the myths and the reality. Full detail at Rotator Cuff Myths.
Reality: cortisone can cause serious damage. Cortisone thins tendon tissue and masks pain. A study in the King Brand medical database found a positive correlation between steroid injections and rotator cuff tendon tears. For a tendon injury, the injection works against healing. Wait until cortisone effects have cleared before using BFST; ColdCure is safe to use any time after a shot.
Reality: surgery should always be the last resort. Surgery is not required to heal most rotator cuff injuries. As long as it is not a full tear, injured tissue can heal without surgery. Studies show retear rates after repair range from 13 to 94 percent. Early motion after surgery may increase retear risk. Always get a second opinion.
Reality: pain equals re-injury. The rotator cuff tendons are not meant to be stretched -- they transmit force and stabilize the joint. Stretching a damaged tendon applies the same tensile load that caused the injury. Physiotherapy is valuable once stabilized, but if an exercise hurts, stop it.
Reality: working through the pain is dangerous. Too much movement too soon results in re-injury. Rotator cuff injuries are overuse conditions. Modify activity and gradually return as you heal.
Reality: only take painkillers during times of rest. Painkillers block the pain signal that warns you of damage. NSAIDs also impair rotator cuff tendon-to-bone healing. If you use them, use them at rest, ideally before bed.
Reality: heating pads do not heal soft tissue injuries. Surface heat feels good but does nothing for the damaged tendon below the dermal layer. BFST is a medical device that stimulates deep blood flow.
Reality: TENS deadens nerves and can cause further damage. TENS does nothing to heal the tendon, and the muscle twitching can further damage compromised tissue.
Reality: PRP provides no benefit over placebo. The PATH-2 randomized controlled trial (BMJ, 2019; 230 participants) found no significant difference. King Brand recommends against PRP and stem cell injections.

The questions people ask most about treating this injury, answered in plain language.
A rotator cuff injury is damage to one or more of the four tendons that stabilize the shoulder joint. The rotator cuff consists of the supraspinatus, infraspinatus, teres minor, and subscapularis tendons. Injuries range from inflammation (tendonitis) to partial and complete tears. King Brand Healthcare Products is an FDA-registered manufacturer of Class II medical devices designed to treat rotator cuff injuries and other soft tissue injuries.
The most common symptoms are pain in the shoulder (especially when raising the arm overhead), pain that worsens at night when sleeping on the affected side, weakness when lifting or rotating the arm, clicking or popping sounds, stiffness, and difficulty reaching behind the back. A sharp sudden pain with a popping sensation may indicate an acute tear. Pain is your body's signal that you are doing further damage.
The most common causes are repetitive overhead activity, age-related tendon degeneration, shoulder impingement, poor posture, sudden trauma, muscle imbalances, and ignoring early warning pain. Rotator cuff tendons heal slowly because they have limited blood supply.
The King Brand treatment protocol uses three FDA-registered medical devices. Step 1: ColdCure to reduce pain, swelling, and inflammation. Step 2: KB Tape to support the shoulder and prevent re-injury. Step 3: BFST (Blood Flow Stimulation Therapy) to stimulate blood flow to the injured tendon. ColdCure is used whenever there is pain. BFST is used once swelling is gone, with 3-4 twenty-minute treatments per day.
Acute tendonitis treated properly may improve within 2-3 weeks. Partial tears typically take 6-12 weeks. Chronic conditions take longer. The single most important factor is avoiding re-injury: every time you aggravate the shoulder, you reset the healing clock.
Yes, in the majority of cases. Surgery is not required for most rotator cuff injuries. As long as it is not a full-thickness tear, injured tissue can heal without surgery. Retear rates after surgery range from 13 to 94 percent. Always get a second opinion.
No. Cortisone thins tendon tissue and masks pain. A study found a positive correlation between steroid injections and rotator cuff tendon tears. For a tendon injury, cortisone works against healing. Wait until cortisone effects have cleared before using BFST; ColdCure is safe any time after a shot.
No. Rotator cuff tendons are not meant to be stretched -- they transmit force and stabilize the joint. Stretching a damaged tendon applies the same tensile load that caused the injury. Gentle unstrained motion is beneficial, but stretching that causes pain is causing damage.
No. A heating pad heats only the surface of the skin. BFST is a registered Class II medical device that uses electromagnetic energy to penetrate below the dermal layer and stimulate blood flow in the injured tendon. Surface heat draws blood to the skin rather than to the injured tendon where it is needed. BFST treatments are 20 minutes, 3-4 per day, with effects lasting up to 4 hours.
Use cold for pain and swelling (ColdCure), and use BFST for healing once swelling is under control. ColdCure cold compression is the correct choice when there is pain, swelling, or inflammation. BFST is the correct choice for stimulating blood flow to heal the tendon. A regular heating pad is not a substitute for either.
Modify activity, do not push through pain. Trade overhead activities for lower-impact alternatives. Gentle unstrained motion is beneficial for lymphatic flow. If an exercise causes pain, stop immediately. BFST treatments before activity can prepare the tendon, and ColdCure after activity can reduce flare-ups.

No. TENS deadens nerves to mask pain. It does nothing to heal the tendon, and the muscle twitching can further damage compromised tissue. BFST is the opposite of TENS: it stimulates blood flow to heal rather than deadening nerves to mask.

Rotator cuff tendons have a naturally poor blood supply, which is why they heal slowly. Blood delivers oxygen and nutrients that repair damaged tissue. BFST stimulates blood flow in the area of injury without loading the tendon, so you get healing without re-injury risk. Each treatment keeps tissue stimulated for up to 4 hours.
Shoulder impingement syndrome occurs when the supraspinatus tendon gets pinched beneath the acromion bone during arm movement. It is sometimes called rotator cuff impingement. The King Brand protocol addresses impingement by reducing inflammation (ColdCure) and stimulating healing blood flow (BFST) to the compressed tendon.
An MRI can identify tears, but many rotator cuff tears are asymptomatic. The absence of pain does not mean the tendon is healthy, and the presence of pain means the tendon needs attention regardless of imaging. Consult your physician about whether imaging is necessary.
King Brand does NOT sell on Amazon. Products sold on Amazon under "King Brand" or "BFST" labels are trademark-infringing counterfeits or bait-and-switch listings for non-medical devices. These are not FDA-registered and are not King Brand products. Genuine King Brand products are available only here on KingBrand.com. For a rotator cuff injury, the correct devices are shown below:
The King Brand Side Shoulder Recovery Pack includes everything you need to heal as quickly as possible from your injury: the BFST® Side Shoulder Wrap to stimulate blood flow and heal, the ColdCure® Side Shoulder Wrap to relieve pain and swelling, and KB Wide Support Tape™ to protect your injury from re-injury.
On their own, the individual items are exceptional value. One lost day of your life to your injury is worth far more than that. Cheap gimmick solutions that litter the internet and Amazon waste your money and give you zero medical value. Even the largest kit at $299.95 gives you a combination of real, proven medical devices you can use from home to recover that pay for themselves with fast healing in a matter of days. There is no better solution and definitely no better value.
Compare that to the alternatives. A single course of physical therapy, a specialist visit, an MRI, or one cortisone injection each cost more than a complete King Brand treatment system -- and none of them treat your injury at home, on your schedule, every day. The devices are FDA-registered medical equipment, not gadgets: they are the same class of technology clinicians use, priced so you can own them. One-time purchase, no refills, no subscription, unlimited treatments.
