From last few days, I have been experiencing some itchy sensation across the body with tiny red spots/bumps on the hands and chest. This happens immediately after exposure to sun/heat for sometime and then subsides in 15-20 minutes. In this period of time, there is kind of irritation and itchy sensation across the body including scalp. I am 29, do not have any known allergies (food,cosmetics) and I am used to playing outdoor sport under the sun. There is no change in my food and lifestyle in the recent past. The only change I see is the intermittent weather. Rain, cold, sun changing rapidly nowdays. I spend most of the day in AC during my work as a s/w engg. My sweating is also normal as per physical activity. I have consulted a regular physician who prescribed some anti-allergic pills. The severity has reduced a bit, but when there is sudden change from indoor(AC) to outdoor, the itching and tiny redpost/bumps are back. The last I had a blood profile test was within 1 year and the report is normal. None of my parents are diabetic.
Is this because of dry skin ? Do you suggest any cooling body lotion.
