Brief Answer:
Possible fungal or eczema rash.

Detailed Answer:
Hello,

Thank you for using Healthcaremagic to post your health query.
I read carefully your question and I saw carefully your photos.

From what I am seeing it may be like a small patch of a fungal infection or eczema. It is localized in an area where can be humid from the sweating so it makes the area prone to develop this kind of infections.

I would recommend to apply Ketoconazole 2% crema, twice/day for 2 weeks.
If not better after the first week, or if worse, then switch to Hydrocortisone 1% cream, once/day for 1 week.
Try to keep that area as dry as is possible.

If worse or not better, I would recommend seeing a local doctor.

Hope this is helpful.
Let me know if you need more clarifications.


Regards,
Dr. Papaqako
