Had developed "mechanic`s thumb' where my left thumb would "lock" closed. Was able to get the 3 cortizon shots and that "fixed it". Now having the same problem with the right, and if i`m not careful it will bring tears to my eyes. I absolutely DISPISE shots, but it`s getting time to "bite the bullet again". I really LOVE how they try to tell me "You won`t feel this needle getting jabbed 3/4th" into your painful joint"...REALLY ? PROMISE ?
