Thanks, Dr. Kaur.
I will apply your recomandation.
Hello,
I cannot confirm anything without examination but it can be infected hair follicles, sweat dermatitis, heat rash or contact dermatitis. Take some antihistaminic like Benadryl or Zyrtec and apply some calamine lotion on the itchy areas. If the symptoms persist then you may need topical and oral steroids. Please consult a dermatologist in that case.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your dermatologist. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
