It also feels as though I cannot stretch my thumb as far from my other fingers as on my other hand
. The muscle between my thumb and index finger
shows no sign of wasting; it's actually more plump than on the other hand. Also, when I pick heavy things up (like a carton of juice), sometimes I get a sharp pain in my wrist, and this pain sometimes extends into my hand. Last, my pinky feels quite stiff in the morning and, although it feels better through the day, does not feel all better.
