I am allergic to pineapple and ate some accidentally last Monday (a week ago tomorrow). Since then I have had a lot of tingling in my mouth, tongue, lips and throat. I took Benadryl and went to urgent care, where they gave me a prednisone shot and prescribed Claritin and Zantac along with the Benadryl. The symptoms went away for hours at a time but kept coming back, so I would take Benadryl again. By Friday it had gotten worse and I went to the ER, feeling that my throat was filling up or swelling. In the ER I was given more Benadryl, was prescribed a medrol dospak and given a penicillin shot, as they discovered I had strep throat also. I am now getting the same tingling, mouth burning symptoms more frequently and taking Benadryl more frequently, along with the Zantac and prednisone, and becoming very anxious. Shouldn t the pineapple allergy be gone by now, or am I reacting to something else?
