I am 23 years old, and i had chronic sinnusitis for almost 2 years now. I am having very bad muscle twichting and pulsating at my left side of the nose. It s been like this for 2 weeks now, but it always comes and goes away. But today, i had this issue the whole day ever since i woke up and it hasn t stop until then. I am going crazy and i d really apreciate an advice from a doctor right now. Please help me, what do you think it could be???
