1. You should wear neat innerwear. 2. You should not use innerwear more than one day. 3. Keep your Bumps from perspiration. 4. Use Clotrimazole cream as directed by a physician. 5. Wash with hot water added salt.
If it looks very severe the best thing to do is to call your local doctor and have them run some tests and try to help them out on what you have been doing when you got those bumps or bruises to let the give you what you really need.
