What should you know about intertrigo burning?

Intertrigo affects areas where skin touches skin, such as the groin, underarms, beneath the breasts, abdomen or between the buttocks. Friction can make the surface feel raw, hot or stinging. Sweat and trapped moisture soften the outer skin and allow irritation to persist. A red or darker patch, soreness, itching, scaling, cracks or a moist surface may occur together. A yeast overgrowth can add a sharper itch, small nearby spots or a more defined edge; see [Skin Yeast Infection](/conditions/cutaneous-candidiasis/) for related information.

Burning is a symptom, not a diagnosis by itself. A clinician may consider contact dermatitis, bacterial infection or another rash when the appearance or response to care does not fit ordinary intertrigo. [Intertrigo](/conditions/intertrigo/) provides broader condition information.

Gently wash the fold, rinse away cleanser and pat it completely dry. Choose loose, breathable clothing and change damp garments promptly. Reduce rubbing by keeping the fold separated with a clean, dry layer of fabric; avoid scrubbing, fragranced products and home remedies that sting. Do not apply steroid or combination creams without medical guidance, because they can obscure an infection or irritate fragile skin. If yeast is suspected, a clinician or pharmacist can advise whether [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) is suitable. Persistent sweating may warrant discussion of [Prescription Antiperspirant](/treatments/medical-dermatology/prescription-antiperspirant/).

Arrange medical assessment if the burning is severe, spreading, recurrent or not settling with gentle drying and friction reduction. Seek prompt care for rapidly increasing redness, warmth, swelling, pus, blisters, open sores, fever or feeling unwell. Diabetes, immune suppression or a history of repeated fold infections lowers the threshold for an examination. A new [Skin Rash](/symptoms/skin-rash/) or associated [Itchy Groin](/symptoms/groin-itching/) can help describe the problem, but neither link replaces an assessment.

Ask whether the appearance suggests yeast, bacteria, contact irritation or friction alone; which product is appropriate for this fold; how long to use it; and how to prevent moisture and rubbing from returning.
