The answer is no, your pain and swelling do not have to be completely gone before you can use the BFST. For best results, you should use the ColdCure exclusively until you notice a definite decrease in pain and swelling. This indicates that your inflammation is decreasing, and the less inflammation you have, the more effective your BFST treatments will be.
If you notice an increase in swelling, or sharp pain, that may be a sign of inflammation. You can reduce this inflammation by using the ColdCure. To streamline your treatments, you can use the ColdCure first, then wait for your skin to warm up to body temperature, and then apply the BFST. BFST treatments should be spaced at least four hours apart.
