<s>[INST] i have itchy, little bumps and welts that can I can watch appear. I have not been near any poison ivy, oak, or sumac. I have a bunch on my chest . Haven t changed soap, laundry cleaners or eaten anything new. Not bug bites as I get them even when I am at work in a hospital. Antihistamines are not helping so I am wondering if they are from stress . I work a lot, plus have 2 kids, a knee surgery coming up and a vacation in a month. Is there anything more that I can do to stop this? [/INST] Hi, After reading your history it appears that you urticaria or hives. This is common problem, and we see so many of cases in normal population. So do not worry about it. There are so many of the aggravating factor and in yourself including day to day factors of environment. You can take loratadine or levocetrizine or fexofenadine daily. You can apply calamine lotion over the affected area. Stay away from hot and humid climate and wear cotton clothes. </s>
