I had 3 injections on 3/9/15 in the E.R. they were Zithromax, rocephin and solumedrol. One the the injections I about flew off the bed from I had really really bad burning after being injected it was especially bad in the groin area and it lasted for about 30 seconds or so. I felt like I was burning from the inside out. Out of these 3 injections do you know which one could have gave me that symptom? I want to make sure I never have it AGAIN!!!
