All of a sudden half of my fingertip on my left index finger is numb. It's a really small space (not even a square centimeter) and hardly noticeable but it's freaking me out! I've been sitting slouched against a wall typing up some schoolwork most of the day, maybe I pinched a nerve in my back or something in my hand from typing for a few hours? I looked it up and that can cause the numbness...I'm just a little freaked out because it's a weird sensation, but I'm trying to tell myself that the fact that it is only half of one fingertip means it's most likely not a serious issue, but the irrational anxious side is telling me it's a blood clot, diabetes (even though I don't have it some of my relatives do and I worry about it constantly), etc. What do you think it is? I'm away from home right now, going back in 2 weeks but I can't see a doctor unless it is an emergency. I just need some other people to talk to who understand anxiety and can help me figure out what is going on.
