I had many nodules/lumps in my right palm with stage I contracture of pinky and thumb caused by cords. I had NA that released the cords then radiation therapy. RT stopped the progression so far, stopped the itchy/crawly feeling in my palm.
You sound like a possible candidate for both NA and RT.
Research everything in the menu options on the left. Look for lists of providers of NA and RT. Take pictures of your hand and email them to the providers of NA. That's what I did and got immediate response. For RT, you will probably have to go in for them to see your hands. NA is usually done first, then RT.
