<s>[INST] I am a 45 year old female. Yesterday the palms of my feet and hands were itching and I was having chest pains off and on. I took Benadryl and the itching went away. Today the itching returned and I got a rash on my body and now I also have red spots on my arms. I also had a headache. I took advil and Benadryl and the itching and headache went away but I still have rash. Do you have any idea of what I could have? [/INST] Hello, You seem to have Hives. I suggest you use a soothing lotion e.g calamine lotion. In addition, I suggest you take an oral antihistamine e.g either Cetirizine tablet or Loratadine tablet once a day for a few days. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Kakkar S., Dermatologist </s>
