<s>[INST] every year when the weather gets a little warmer my skin starts to get itchy and small red bumps appear..usually on the back of my hands and forearms, legs and face sometimes neck and chest but appear anywhere randomly. they are usually clustered together. i havent applied anything different to my skin that i would normally use, and i have no known allergies. this only happens in the spring/summer time, and it doesnt even have to be really hot. it happens even when im not in the sun. what could this possibly be [/INST] Hello. Thank you for asking at Chat Doctor. I went through your history and would like to make suggestions for you as follows:1. From your history, I would first think of urticaria.2. They can be self-limiting, usually in response to change in environment like temperature or humidity. They can also occur due to sweating or increase body heat.3. I would suggest you to take antihistamines like levocetirizine for symptoms relief.4. I would also suggest you to apply lotion like calamine over itchy areas.5. Please do not scratch itchy areas as scratching aggravates itching.6. In general, I would suggest you to avoid too hot/spicy foods/beverages, activities causing excessive sweating and tight-fitting, woolen clothes. In my opinion, loose-fitting, cotton clothes would be a good option. Hope above suggestions will be helpful to you. Should you have nay further query, please feel free to ask at Chat Doctor. Wish you the best of the health. Thank you & Regards. </s>
