I had a spider bite sized sore on my back and it never really closed for about 2 weeks so finally i put preasure on it and i was able to push out two small balls about the size of a small seed (along with alot of puss & ect). I was just wondering what this might be, is it just like a stinger that was left in my body to long and built up calcium around it or could it be serious?
