In the last month or so i have experienced an itch in my groin/thigh area and on my arm pit. there isn't a rash but there are inflamed bumps?

Yeast??: These are common areas for yeast infection. One of the most common causes is incomplete drying off after a shower or bath. It's an easy dermatological condition usually very easy to treat. If you are diabetic and/or obese it is more common. Please see your primary care physician. Also try to avoid tight fitting clothes & underwear for at least a week.
