When the nerve endings in the nasal cavity are subjected to adverse stimulation from outside, a nerve reflex, physical or chemical stimulation can occur. The disease is mostly seen in simple rhinitis, or early symptoms of common cold, but also in acute rhinitis, allergic rhinitis and other cases. In general, cancer rarely causes frequent sneezing, but one needs to be alert to the possibility of sinus cancer.

If the above-mentioned adverse symptoms suddenly appear, it is recommended to go to the ENT department of hospital for examination in time. It is recommended to take regular rest and rest, exercise more, enhance physical fitness, improve your immunity and avoid colds.
