<human>: I get red blotches that itch terribly on my feet when I walk in the grass, sometimes on my arms, legs, etc. just when I go outside. I have many allergies which include mosquito bites. At first I thought this was an insect bite but,,, I went wsimming in my pool yesterday and was covered in these red blotches. Showered, put witch hazel on (which seems to work better than anything else that I ve tried) and took a Benedryl. Went away in an hour or so. Any ideas?
<bot>: Hello. Thank you for asking at Chat Doctor. I went through out history and would first think of "urticaria" (hives). I would make following suggestions to you:1. Furthermore, I usually suggest my such patients an antihistamine like cetirizine or levocetirizine or HY Chat Doctor. 2. Furthermore, I also suggest them application of a lotion like calamine over itchy areas.3. There are many causes of urticaria - both allergic and non-allergic. I would suggest you to avoid substances you may be allergic to.4. I usually also advise my urticaria patients to avoid exercises causing excessive sweating, too hot/spicy foods and tight-fitting, woolen clothes. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at Chat Doctor. Wish you the best of the health. Thank you & Regards.
