this morning I woke up and I had a lot of itching on my left ring finger tip, almost like a mosquito bite that wouldn't go away, kind of itch. later after that, I had tingling, sometimes hurts if I set it down on something without remembering about it. I have a weird kind of numbness to it as well. I can feel my thumb nail wen I use it to put pressure on my ring finger, but its not the same as the other hand. to me it looks a little swollen and a tiny bit discolored. I just read online that it could be caused by the nerves in your neck and I remember when I went to bed last night my neck and head were a little sore, and couldn't get comfortable. what do you think?
