In the last 4-6 weeks I keep getting this rash on and off on both of my arms. It's a red and lumpy rash. Looks like mosquito bites. It itches a little then goes away after an hour or more. Then a day or 2 later it comes back. Just wondering what this might be? Possibly hives or some sort of an allergic reaction? Any help you could give would help thanks.
Thanks for your reply doc, i logged in under a different name but its still me malibuaz1234. Anyways i have no intentions or plans on seeing a dcotor or anything and i dont need any itching creams or anything because it never itch only when it was just starting to come in and plus its not even there anymore. By the time i wrote the original question to you it was already gone. It pretty much looked like an average diaper rash. I was wondering what it was and what caused it.
It sounds as though it may be hives, which come and go the way you describe. Despite their allergic reputation, the vast majority of hives are not allergic--they come for no reason and go away the same way. While you're waiting to see a doctor, you can use an over-the-counter anti-itch lotion containing camphor, menthol, or pramoxine. As for HIV, I see no reason for you to worry about that. If the rash is still there after the weekend, let a doctor check it out.
Best.
