I have itchy dry red bumps on my skin. The dry ones are like the scab healing. The other red ones are new. They are mostly on my stomach and back and get worse during my menstrual cycle. I started taking a probiotic for other reasons and it cleared up my skin. Soon as I don't take them my skin flares up again.
Hello,
Unfortunately I cannot confirm anything without examination but it can be contact dermatitis, allergy, sweat dermatitis, heat rash or scabies. The bumps on the scalp sound like folliculitis. Avoid using any lotions and creams for the meantime. Use a mild cleanser with moisturizing properties like Cetaphil. Also use cotton clothes and change the clothes twice if there is any increased sweating. Try keeping the skin free of sweat as far as possible. If the symptoms still persist then you can apply mild steroid like dermacort. For the itching antihistaminics like Benadryl or Claritin can be taken.
If the symptoms persist then please get it examined from a dermatologist. 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.
