Hi and thanks for the query, the very first thing to do is to get a proper clinical examination preferably done by an ENT specialist. This is particular important for an appropriate diagnosis facilitates treatment. The cause could b infectious(bacterial, viral, tumot, traumatic, fungal), and an appropriate diagnosis determines the appropriate treatment. Blood pressure deserves a more careful attention. Meeting your primary care physician to guide you on the life style changes like stopping smoking, exercise, rich vegetable diet and low salt diet. Consult your ENT specialist and family physician for care, best regards, Bain LE, MD.
