My building contractor's wife just told me he is going to a hand specialist tomorrow.
When she married Rob (about 17 years ago) his ring finger was size 11.
Now his pinky finger is size 18!
For comparison, my DH began at size 10.5 ring finger, is now 70 lbs. heavier and wears size 13.
Rob's hands are like baseball mitts. They are numb, except during the night when they throb and keep him awake.
No other body parts have grown disproportionately, and there is no other numbness.
Any guesses as to what you think this malady could be?
BTW, he can still use his hands to pick up large things such as a hammer, but cannot negotiate little things like screws.
