My thumb started popping several weeks ago, now it is bending the wrong way on the joint. I spoke to my doctor about it and in addition to changing my biological he sent me to occupational therapy. I had my evaluation yesterday and start therapy on Friday. They took measurements and function test and found both hands to be well below average but the thumb that is hurting measured to only 5 lbs of strength. She did recommend a contrast bath. Immersion in hot water for 4 minutes then cold water for 1 minute repeat 2 times and end with 5 mins of hot water.
