I had an allergy test yesterday.  The scratch test, which consisted of dipping a multipronged plastic device into the allergins and then pushed hard on my forearm, produced large welts on my arm and allergy was noted.  I was given reactin at the time.  The swelling and redness has continued and worsened since yesterday.  I went to a walkin clinic and was prescribed a steroid topical and benedrl which I have used since last night.  The redness and swelling have increased and the itching is unbearable.  Might this be an infection?  The technician was new, I was her first ever patient!  Thank you for your help!
