Hello,
From the symptoms it can be an allergic reaction or contact dermatitis. For the itching take some antihistaminic like Benadryl. If the symptoms persist then please get an evaluation done 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 doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
