Brief Answer:
Possibility of Intertrigo

Detailed Answer:
Hello. Thanks for writing to us at healthcaremagic

I am Dr. Kakkar. I have gone through your query and I have understood it.

I would keep a possibility of Intertrigo, which is inflammation of the body folds. Intertrigo clinically presents as red, moist, scaly, sore patches of skin on closely opposed body folds like axilla, groins, submammary folds etc.
Closely opposing body folds trap sweat and moisture and therefore make the area prone to inflammation from rubbing against each other.
Candidal infection may superimpose (Candidal Intertrigo) thereby exacerbating the inflammation (redness and soreness).

You may use an OTC topical antifungal e.g clotrimazole 1% cream, twice daily in the affected folds for 4- 6weeks.
If I was the treating doctor I would have also started you on oral antifungals e.g Oral Fluconazole, in addition to the topical antifungal cream for 4-6 weeks
Oral antifungals are faster acting and better in controlling the candidal superinfection. Oral antifungals are prescription drugs.

It is important to keep the folds dry and therefore, I would suggest you to discontinue using moisturizers in the folds.
Once the condition has improved significantly on topical and oral antifungals (usually within 2-4 weeks), you may use an antifungal dusting powder e.g clotrimazole dusting powder in the folds, twice daily, for maintenance of improvement.
An antifungal dusting powder not only keep the folds dry but also inhibits the growth of fungus/yeast thus preventing recurrence/exacerbation of Intertrigo.

I suggest you to present yourself for examination to a dermatologist for a confirmatory diagnosis. Your dermatologist will tell you more about this condition and how to prevent it.

Regards
