<s>[INST] hello,I've had a minor rash on my upper left thigh for three weeks. I have to look close to see it, but a few small red areas can be seen. sometimes it itches, most of the time it doesn't. it has looked the same since i first noticed it. any ideas? thanks [/INST] Hello. Thanks for writing to us at healthcaremagicI will keep a possibility of fungal infection/tines cruris.Involvement of Inner thighs and folds is classical of tines cruris. It may be unilateral or bilateral.Itching is a feature in fungal infections.I would suggest that you may use an OTC topical antifungal e.g clotriamzole 1% cream, twice daily for 2-4 weeksAn OTC oral antihistamine e.g cetrizine 10 mg once daily will provide you symptomatic relief from itching.If the rash does'nt respond as expected Or if it worsens, you may visit a specialist dermatologist for a review.Regards </s>
