Recently about two weeks ago I started to have this weird twitching on my top left scalp. It felt like as of a bug or something is crawling on it too. I have no idea what it can be causing this. I hope it is related to stress, cause I was pretty stress lately. There are also some small like pimple popping up too that doesn't itch but hurts a lot. I have had the pimple couple times before but not the twitching along with the numbness sensation. I hope it's not something life threatening. I am a married man with three girls and working full time. I think it's time for a doctor visit soon to see what's really going on. Any advice would be gladly appreciated.
