I have been getting the depo shot for a year now, however I went on 8/15 and had my most recent shot. The next morning I woke up with a horrible itch skin rash on my back that later spread to my neck, breasts, arms, legs and stomach. I went to the dermatologist and they did a Biopsy which showed that it was an allergic reaction, but when I contacted my OB they said I couldn't have gotten it from the shot if it hasn't happened before. I was on methyprednisolone for 6 days and I thought it was getting better but exactly 1 week has gone by after the last pill and it's coming back and worse than before. Please help me.. I have an appointment with an allergist coming up but I need to know what to do before then.
