Hello. Thanks for writing to us at healthcaremagic

I am Dr. kakkar. I have gone through your query.

Kindly upload a few clear digital photographs of the rash so that I am able to understand and guide you better. I can be either be a fungal infection (Tinea Cruris) or it can be Erythrasma (caused by corynebacterium), but i will more sure once I have a look at it.

Tinea versicolor is unusual on the legs, it commonly occurs on the shoulders, trunk area.

Brief Answer:
Fungal Infection in the groin folds

Detailed Answer:
Hi. Nice to get in touch with you again :)

I have reviewed the photograph

No its not anything major. In the photograph, I can see some redness/ inflammation and scaling in the convexity of the groin fold.
This seems like a fungal infection/tinea cruris. Itching is subjective, and absence of itching does'nt rule out a fungal infection

If I was the treating doctor I would have asked you to use an OTC topical antifungal e.g clotrimazole 1% cream, twice daily, for 2-4 weeks.
That should make it fine.

Brief Answer:
Clotrimazole is OTC; Rash not linked to STD's

Detailed Answer:
Hi.

Clotrimazole 1 % cream is available OTC from a drug store.

Negative test for STI's, after 4 months of a risky sexual encounter is conclusive as it is well past the window period for detection of HIV (3 months) and the generally accepted duration for a blood test to become positive after a possible infection, which is 1-3 months for a VDRL/RPR for syphilis; 7-10 days for IgM for HSV 1&2; 2 weeks for gonorrhea and chlamydia by swab test; and 2 weeks for a positive serology for hepatitis b; hep c is anyways very very rarely transmitted sexually.

The fungal infection has nothing to do with STDs
