Brief Answer: Likely to be due to dermatitis. Detailed Answer: Hello, Thanks for posting your query. I have seen the picture attached. The rash seems to be due to contact dermatitis. A direct examination by a dermatologist is the best way to get it diagnosed. Most of such simple rashes improve with gentle skin care and avoiding irritating substances. You can help the improvement by * Avoid scrubbing your skin. * Use as little soap as possible. Use gentle cleansers instead. * Avoid applying cosmetic lotions or ointments directly on the rash. * Use warm (not hot) water for cleaning. XXXXXXX dry, don't rub. * Eliminate any newly added cosmetics or lotions. * Leave the affected area exposed to the air as much as possible. * Try calamine medicated lotion. * Hydrocortisone cream (1%) is available without a prescription and may soothe such rashes. The rash usually take 5-7 days to disappear. You can also take an anti allergic like cetrizine orally to help with the improvement. If the rash becomes more of purple rather than red then you must consult a dermatologist immediately. I hope this answers your query. In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out. Wishing you good health. Regards. Dr. Praveen Tayal.
