Hello. Thank you for asking at HCM. I went through your history and first of all I would think of what is known as Solar urticaria (itching with rash due to sun exposure). I would like to suggest you as follows: 1. Prevention is the best treatment for this type of allergy. Please try to avoid direct sunlight by suitable clothes. 2. I would suggest you to apply sun block creams with SPF (Sunlight Protection Factor) 15 or more before anticipated exposure to sunlight. 3. Personally I would suggest you to take foods rich in vitamin A (retinoids) like carrots, green leafy vegetables, mango, other yellow or orange colored fruits, etc. Retinoids can improve solar energy. 4. In spite of above measures, if you develop itching and/or rash following sun exposure, I would suggest you to take an antihistamine like cetirizine or levocetirizine immediately, which will help. Hope above measures will be helpful to you. Sunlight allergy is usually a very benign condition. Sometimes it subsides by itself within a few months/years. It does not have any serious consequences. Please do not worry about it. Should you have any further query, please feel free to ask at HCM. Wish you the best of the health. Thank you and Regards.
