<s>[INST] I m extremely itchy all over my body, the itch happens mostly at night, and in my room. I have washed my sheets and and now even on a sheet-less air mattress. The itch occurs at all points of my day except when I am in the shower. Baby powder and cortisone doesn t help at all. The itch is mostly on my chest, thighs, arms, and hands (and avoids the pubic area). PLEASE HELP I don t have any sort of bites; but I have noticed that much of the itchy areas house small red dots, and when I get out of the shower, some areas of my skin get very red (but are relieved). [/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 description, I would first think of "urticaria", which can be due to allergies or non-allergic causes too.2. I usually prescribe my such patients regular antihistamines like levocetirizine or cetirizine or HY Chat Doctor. 3. I would also suggest you to apply moisturizing lotion/cream over itchy/ </s>
