- Pat rash dry instead of rubbing.
- Let the rash breathe—do not cover with clothing, if possible.
- Stop using new cosmetics or lotions, as these may have triggered the rash.

- An oatmeal bath can soothe rashes caused by shingles, eczema, or psoriasis. Moisturizing lotion may help eczema symptoms.
Dandruff is caused by weather, oily skin, stress, fatigue, or not washing one’s hair enough. Dandruff can usually be treated by washing your hair and scalp regularly with dandruff shampoo. Medicated dandruff shampoo is commonly available at drugstores, though your doctor can prescribe stronger types.
You can take acetaminophen or ibuprofen for mild pain associated with the rash. Check with your healthcare provider before taking these drugs if you have liver or kidney disease, or a history of stomach ulcers or GI bleeding.
