<s>[INST]Hello Dr Grief. I dont have any allergies to any food or medicine but after eating a non quality ham in a trusted restaurant the 3 of us started to itch in less than an hour. Even if we took loratidine, it did not stop the hives like rash. Any possibility?[/INST]Hi, The symptoms are pointing towards allergic reaction only with a possibility of any spoiled or expired ingredient in the burger that is causing you a rash.  So if the symptoms are not getting better you can consult an Emergency room and get evaluated and a blood test can be done to rule out the cause.  You can also be advised a steroid shot along with oral anti-allergics to relieve the symptoms faster. Also doing ice packs over the rashes and applying Call Chat Doctor.  </s>
