Red rash near mouth

I have been to numerous doctors and a dermatologist to try to ascertain what my skin problem is. One suggested it was rosacea, one said it might be dermatitis and the dermatologist said it could be those or lupus. Over many months I have had a raised red rash,near the left side of my mouth but also some on the right side of the mouth. I also develop, at different times, redness all over my face (particularly across the nose and cheeks) like sunburn.  This comes on then passes after a half hour or so. There is also an area of redness at the top of my arm , within a circular area. I am currently consulting a dietician to ascertain whether it might be food related.   I also find my facial skin is extremely sensitive and I cannot use any products on it.

Any ideas as to what this might be? Thank you.

Hello,
It can be contact dermatitis, lupus or rosacea.  Rosacea is a cutaneous disorder i.e. of the central part of the face such as forehead, cheeks, nose and chin. Pimples are sometimes included as part of the definition.

Treatment options vary from antibiotic creams, antihistaminics, sun screens to laser treatment. A dermatologist’s evaluation will be the best 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.
