Hi, Thanks for the info. I've had some of the inj but they only seem to work for so long. One trigger finger I had just wouldn't be helped so they did the release and the best part of that was it doesn't bother me anymore however each finger has one and the thumb is a different problem for which I've had the inj for and if I want to continue my ways I just deal with the pain and put the blue stuff on. I can't get the inj to often. the hand Dr I go tp said we'll keep your hands going don't you worry it's good for your brain to keep moving them the way you do. that's for all of us who refuse to give in to the pain and sit back and do nothing. good luck to all of us. Sue
