When I get my period, I get pimples on my underside that are very itchy.

The extremely itchy pimples under the menstrual period may be related to menstrual vulvar dermatitis, vulvar eczema, contact dermatitis, vulvovaginal candidiasis, bacterial vaginosis and other factors. It is recommended to seek medical treatment promptly for a clear diagnosis and carry out targeted treatment under the guidance of a doctor.

1. Menstrual vulvar dermatitis

Using sanitary napkins or panty liners during menstruation may lead to poor air permeability of the local skin, causing friction and irritation to induce dermatitis. It manifests as vulvar erythema, papules and itching. It is necessary to change sanitary products with good breathability and avoid scratching. You can use calamine lotion or hydrocortisone butyrate cream as directed by your doctor to relieve symptoms.

2. Vulvar eczema

Decreased immunity during menstruation may induce eczema, which manifests as symmetrically distributed papules and blisters accompanied by severe itching. It is necessary to keep the vulva clean and dry and avoid hot water scalding. You can use tacrolimus ointment or triamcinolone acetonide and econazole cream as directed by your doctor.

3. Contact dermatitis

Allergy to sanitary napkin materials may lead to contact dermatitis, which manifests as redness, swelling, and papules with clear borders at the site of use. It is necessary to stop using the allergenic product immediately, rinse with water, and follow the doctor's advice to take oral loratadine tablets and desonide cream for external use.

4. Vulvovaginal candidiasis

The moist environment during menstruation can easily breed Candida, which manifests as vulvar itching, bean-like leucorrhea, and scattered papules. It is necessary to keep the vulva clean and avoid wearing tight pants. You can use clotrimazole vaginal tablets or miconazole nitrate suppositories as directed by your doctor.

5. Bacterial vaginosis

Disruption of the acid-base balance during menstruation may lead to bacterial infection, manifested as gray-white discharge with a fishy smell and vulvar irritation. If you need to avoid frequent vaginal douching, you can use metronidazole vaginal gel or clindamycin phosphate vaginal tablets as directed by your doctor.

In daily life, you should choose cotton and breathable underwear, change sanitary napkins every 2-3 hours during menstruation, and avoid using fragrance-containing care products. Reduce the intake of spicy foods and supplement yogurt with probiotics. If symptoms continue to worsen or abnormal secretions, ulcers, etc. occur, you must immediately seek medical attention for routine examinations such as leucorrhea. Do not use drugs to cover up symptoms for a long time.
