Hello,
Without examination,confirmation of a diagnosis is tough but this swelling can be due to friction rub or chaffing. Chafing is a continuous rubbing of the skin that causes redness or soreness.
Chafing occurs when the skin becomes irritated by the friction caused by rubbing – either against other skin or against a foreign material. Wash the areas several times with fresh water. Do not use any cosmetic products at the sites. You can apply some calamine lotion at the rash as it will help in soothing the skin.Also wear cotton undergarments.Application of mild corticosteroid cream and oral antiinflammatories like ibuprofen/acetaminophen are also helpful.If the symptoms are severe then it will be best to consult a dermatologist.Intertrigo and erythema have to be ruled out.
I hope that helps.Take care and please do keep me posted on how you are doing or if you have any additional doubts.Kind regards.
Thanks for the reply. Will try your suggestions and will keep you posted.
