I first discovered the Backmitra during a yoga class. My right shoulder was extremely tight following a series of radiation treatments, but the Backmitra quickly helped alleviate my discomfort. Now, I make it a daily practice to lie on the Backmitra for a few minutes and I feel so much better having learned how to use it effectively. I highly recommend the Backmitra to anyone dealing with back or shoulder issues. It saves a lot of visits to a masseuse or physical therapist.
