This evening while out eating dinner, I started feeling itchy throughout my body and getting worst. When I got home I noticed I had welts or hives. I have been to the same restaurant several times and ate the same foods. An hour before dinner, I had my hair highlighted (colored) and cut. I was not itching because of lose hair on clothing. I had changed my clothing before we went to dinner. I also noticed that my left leg, ankle and foot is swelled and tight. I put caladryl lotion and took 1 antihistamine pill. Can you tell me what my allergy could be? Is there anything else I can do to treat it? Thank you.
May be some brand of color reacted as it takes some time to appear allergies and once exposed takes 3 weeks to recovers you need to continue the antiallergic pills for 3 weeks and antiallergic ointment after 3 week if recurs consult allergy specialist for finding answer according to history and examination
