My right finger and thumb are tingling and the very end of the first finger on my right hand seems to be going to sleep or numb Super sensitive to hot water with pain in finger........don t know if it s from the arthritis in my hands (since the weather has been crazy lately) , or diabetic nerve pain (since I am pre diabetic on metformin) or something else. My left hand has a similar feeling in the thumb and first finger on the left hand. I sleep with wrist bands on because of repetitive use of my hands for certain task.....is that diabetic neuropathy????? Obviously I am guessing...........Mary C
