Sunday night I just happened to notice a small numb area on the back of my left arm (around the tricep). I thought it'd go away but it hasn't. I had my wife touch that part of the arm while I wasn't looking and I can just barely feel it, whereas in other places and on the other arm I can feel it normally.
The only thing I can think of is Friday night I carried a little drawer and late at night and the next day my left shoulder was very sore. But my arm never hurt. Furthermore when carrying something one uses the bicep and not the tricep.
If it weren't for the carrying incident I'd go to the doctors but I've been waiting to see if it goes away. Sometimes I get a very mild warm sensation down the back of my arm but it's not really bothersome or painful, it just feels like it's getting warm. Lasts a few seconds.
Any ideas what it could be? Should I see the doctor? I hate seeing doctors cause they order all the tests and usually my problems just seem to disappear on their own.
