I had/have rosacea, also, a mild case, that took doctors of several specialties to finally diagnose (I finally went to a big teaching hospital and made appt with the head of the Dermatology Dept). I, too, get the occasional skin tightening, itching and the symptoms come and go at random, no food/drink makes it better or worse. I am sensitive to many things I put on my face, so when I find one that works for me, I stay with it. I also use a cool humidifier inside in the winter and moisturize my face daily after cleaning it. From what I have learned, Rosacea has no absolutes in it's symptoms.
It can be due to rosacea. If there is any dry itchy skin patches, then eczema and contact dermatitis to cosmetics needs to be ruled out. Rosacea is a cutaneous disorder primarily of the central part of the face , such as forehead; cheeks ;nose; and chin.
Treatment options vary from antibiotic creams, antihistaminics, sun screens to laser treatment. A dermatologist’s evaluation will be the best.
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.
