Hello,
Keep the affected area clean, avoid hot showers, tight clothing, or irritants. Avoid scratching. If it is itchy, apply a thin layer of ointment
Hydrocortisone. If it is not itchy, apply
Clotrimazole ointment on the affected area. Applying Lacto-calamine lotion will also give relief. Mild rashes are possible with misoprostol but very rare. Commonly such bumps occur due to insect bite.
Taking antihistamine as a single dose will give relief. Other factors that can cause such symptoms are
fungal infection,
contact dermatitis, or
folliculitis. Ideally, she should get relieve after applying the ointment and medicines as above. In case the bumps rapidly spread, or if she gets fever, fatigue, or other systemic symptoms. get her clinically examined by a gynecologist. She may require getting a few tests done.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
