A Sinus X-ray (PNS view) is a x-ray test of the face. It shows air-fluid levels and thickening in the sinuses. Typical effective dose 0.02 to 0.1 mSv, similar to a few days of natural background radiation (about 3 mSv a year).
General health information, not a diagnosis. In an emergency, call 102. Always consult a qualified health professional.
