Hi, Welcome and thanks for posting your query to Healthcare Magic. After reading your query the closest possibility of your problem appears to be Acute Sun sensitivity . The skin in some person is sensitive to certain environmental factors, in yourself it apers to be direct sun light. This is a condition allergic phenomenon and hypersensitivity to sunlight. Kindly follow the suggestions below: - Do strict sun protection by covering the area of exposure by clothes, wearing hat and goggles. -Apply over the counter calamine lotion 3-4 times a day. -You can do cold water compresses to reduce the intensity of itching. -Do not scratch or rub the skin as it can lead to further aggravation. -You can take oral anti histamine like loratadine or levocetrizine under medial advise. The best measure to prevent this condition is to avoid direct sun exposure for some time. As soon as the sensitivity is reducing you would be felling better. There is no medication as such which can reduce the sensitivity directly. Prevention is the best cure. Despite above measures if the problem is not getting better then it is better to consult a dermatologist for best guidance. Hope these informations will help.
