Small random painful bump
I am getting small, red(often) very painful bump on skin which stays for 2 days very active then disappear in 3 days. Its single every time, usually upper part of body, head, shoulders, back and face. No use of dermatologist visits, antibiotics and cream. A small bump hardly visible causes severe pain 2-3 inches around it. This is happening past 4 years. Please help find a good ayurvedic medicine.
