Well, one of my family members started off with this bug bite type bump. A day later, it started to swell..& everyday it would get worse. It got so huge & really hard & red. Pus would come out. We immediately thought it was a spider bite. WRONG. Then one by one, my whole family started getting them (EXTREMELY PAINFUL!!!) & the doctor said it was a staff infection. This doesnt seem right, though? Is it possible to get a staff infection like that? Once they go away, another one comes back about 2 weeks later.

Thanks!
