[|Human|] I woke up with a small circular rash looking area on my lower back toward my right side.  Laterally elongated characterized by small raised red bumbs.  Slight burning sensation occurs when rubbed otherwise no discomfort accomponies.  Wondering what it might be and what might have caused it.
[|AI|]  Hello. Thank you for writing to USI will keep a most likely possibility of Tina/Fungal Infection. Patches of tines classically present as annular or circular lesions, which may be composed of red, raised bumps forming a raised margin with central clearing. The patches may grow bigger as they expand peripherally. Itching and burning are a feature of fungal infection. A KOH preparation made from the scale can be scanned under the microscope to look for fungal elements. That would be confirmatory. I suggest you to try an OTC topical antifungal e.g. clotrimazole 1% cream, twice daily for 2-4 weeks. An OTC oral antihistamine e.g. cetirizine 10 mg once daily will provide you symptomatic relief from itching and burning sensation. If the lesion does not respond as expected you must review with a dermatologist. Regards
