Wow, there sure has been an amazing amount of coverage on this topic as a result of the olympians proudly wearing their cup marks in competitions this year. Though this may appear 'new' to the main stream, cupping has been used by many cultures for literally thousands of years.
How does it work? By causing some inflammation and pressure, we cause nerve endings to lengthen and stretch. By creating some swelling and inflammation in the body, we encourage the body to heal itself. Generally, patients report feeling like cupping is very relaxing and feels similar to stretching, massage, etc.
