I Was Treated At Hospital At 7:30 Am For Anaphylactic

I was treated at hospital at 7:30 am for anaphylactic reaction to something. Swelling of throat as well as hives and rash on almost every part of the body. I am 38 years old and female. I'm on a medrol dose pack and 50 mg if Benadryl every 4 hours at home. At the hospital I received one dose of epinephrine, three doses 25 mg Benadryl, and Iv solumedrol. Now at 5 pm I started having numbness and tingling in both arms and hands and now tingling in face. I have never had this type allergy reaction. I am a pharmacist. What could be causing this?
