i fell asleep on my arm the other day and it "went to sleep" like one would expect. when i woke up feeling came back to everything except for the bottom of my thumb and the site on my forearm where i fell asleep on it. it has been about a week now and my forearm is still slightly numb where i fell asleep on it and the bottom of my thumb has feeling but it tingles whenever there is pressure on it like it is still "asleep." does anyone have any ideas what could be causing this?
ps - this is my right arm & hand which is also my dominant hand
