What can cause hives on the inner thighs and arms?

Answer by  catysuzgirl2000 (578)

Hives are itchy rashes caused by several factors. An allergy to a medication like an antibiotic or to a food like peanut, kiwi fruit or even a banana will cause hives. Another factor is a bacterial infection. Sometimes, the reason is unknown but some allergens may trigger the release of histamine by the immune system.

You can be reacting to something new you have been using, have you changed bath soap, laundry soap or other recently? Hives can be aggravted by heat and moisture.

It can be caused by perspiration. Try applying talcum powder before leaving the house and again once you get back. You may also try changing deodorants for a couple of weeks and see if there's any change. Allergies to fabrics are less frequent, but still possible.
