I got this spot (there's no really a bump) and it is really sore (I can't sit or have it touching anything...) The other day it had fever in it and its been getting bigger and its really hard. I have a bruise on my lower back leading to it but I know I haven't fell or anything. For the past few days now since I have had it I been getting headaches(I font really he them) and I get at least 2 headaches a day, light headed, stomach problems, feel like I am going to throw up.. Help please
