Hello,
From the symptoms the chances of balanitis or fungal infection are there. I sincerely advise you to consult a dermatologist and get yourself evaluated for these possibilities.Till then, you should keep the area clean, wear lose comfortable clothes to avoid sweating, use a powder to keep the area dry and use calamine lotion at the sites. Oral antihistamine medications would help for relieving itching.
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 doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
The symptoms may be something as simple as dermatitis, a treatable general skin condition. A dermatologist would be able to prescribe oral and/or topical treatments upon a more specific diagnosis. Your profile doesn't provide your location, so it would be difficult to refer you if you're actually located in a different country. Also, if you have insurance, limitations are often applied to in-network doctors vs. out-of-network doctors. Good luck!!
