QUESTION: For about two weeks each month, I experience a rash (possibly eczema?) in my armpits, on my ribcage, and lower legs—typically before and during my period. These are red bumps that itch intensely at times. Clearing the bumps takes a while, leaving my skin bright red for another week. Are there creams to ease the itching and speed up redness reduction?
ANSWER: Red, intensely itchy bumps often signal urticaria (hives). These typically fade within 48 hours. The cause is frequently unclear, but triggers may include foods, contact allergens, medications, or temperature shifts.
Eczema can also appear as red bumps, linked to dry, itchy, hypersensitive skin. Atopic eczema often stems from allergens like dust mites or pollen.
Alternatively, it could be contact dermatitis from an allergic reaction to body lotion or deodorant. Given the timing with your cycle, fluctuating hormone levels may heighten skin sensitivity to otherwise tolerated substances.
For itching relief, I recommend a calming, soothing product. Opt for soap-free cleansers in your hygiene routine.
Extremely dry skin disrupts the hydrolipid layer (skin barrier), making it vulnerable to irritants. Pharmacies offer specialized shower gels that soften water. Consult a dermatologist for a precise diagnosis.
