This ball has been great for my endometriosis and MS issues. Does a great job of getting into the muscles of the pelvis and working out tension from muscle cramps and spasms
Use this for De Quervain's Tenosynovitis in my hands- the large ball to squeeze/ release, the medium ball to massage my hands, wrists, and up forearm, the little ball to really get in the thumb pad muscles/ tendon. Do this daily and it’s helping. I’ve also used the small ball on my neck muscles, into shoulder, and back of head where my neck spasms. And the medium ball along my shoulder blades on my back rubbing against a wall. Gives me relief from muscle pain
