So I use 3 finger technique to strum triplets especially alot of the time going Ring-Middle-Index. I used to do it previously with no problems. Now that I brought it back after stopping for a while (a month and a bit) I've undergone a serious pain feeling like a build up of pressure in the joint if i attepmt to straighten my ring finger. The closer it is to the pinky when trying to straighten it the more sharp the pain. It almost hurts down my rist which could be explained by a tendon injury possibly. Just wondering how my pinky should be positioned as I play to hopefully eliminate the problem. Please help I don't want to encur any further damage.
