question: I woke up one morning to find the right back side of my head somewhat numb. I don't know what to make of it, but it is obviously concerning to me since i have never experienced something like that before. Then i noticed that i was sluggish, very tired, tired eyes. I took a nap and woke up with my neck hurting badly, that was probably from just poor positioning as i layed on top of layers of clothing and went to nap. Then this morning, out of the blue, i noticed what appeared to be like a pus or sac filled with liquid on the outside of my thigh. Any ideas doc?
