Cause I think I got it!! I have an infection and got a strong antibiotic shot. Now I've had my share of shots before but NEVER have I had anything like this. The actual pric didn't feel any different from any but afterwards, OMG I felt like my entire leg and hip was going to fall off from burning. My mother said I turned as white as a sheet. I thought I was having a reaction or something but the nurse said it was one of the most painful shots out there. So now its still hurting and burning off and on. So what was it?? Any ideas?? All I know was a strong antibiotic.
