I have itches on my stomach, arm pit, and thoart. Small bumps appear and they itch like crazy. I have used caladryl clear and doesn't seem to work?

Allergic Reaction. You may be having an allergic reaction or angioedema / urticaria. Try OTC benadryl (diphenhydramine) or other anti histamines (H1 blockers). If no significant improvement, you will need more aggressive anti-inflammatory medication such as corticosteroids once your diagnosis is confirmed.
