I have two red marks that appeared after playing basketball in the heat today. they are smooth and slightly raised, there are no blisters or bumps yet. there is one on each ridge between my lips and nose. They don't itch and they are not hot or irritating. I did kiss a girl last weekend who had no signs of cold sores but I assume that's what these are. any thoughts? I have pictures but I do not see anywhere to upload them. - thanks.
From the symptoms it can be hives, sweat dermatitis or heat rash. Avoid using any lotions and creams for the meantime. Use a mild cleanser with moisturizing properties like Cetaphil. 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 there is any blister which scabs over, then get cold sores ruled out.
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.
Cold sores is caused by HSV1. Pain, burning, tingling, or itching occurs at the infection site before the sores appear. Then clusters of blisters erupt which break down. You need to get some investigations like sample from the sores to identify the virus, culture analysis, Tzanck smear, antigen and antibody studies and blood sampling for antibody studies done to confirm the diagnosis. My sincere advice would be to consult a dermatologist.
I hope it helps. Take care and regards.
