If you're able see a doctor. But if it's only happening during winter my first thought is the dry weather. It's an issue some people in my family have too, which is solved pretty easily with a humidifier. Get a good quality one and put it in the room you hang out in most/central to the house and leave it on through the winter. It ups the moisture content in the air, which dries out due to the cold weather, and can help with this. Though I still suggest a professional medical opinion as well, just in case it is something more serious.
I'm not a doctor so I'm talking from experience. In some cases this can be easily fixed, you just have to go to the otorhinolaryngology. They can do a cauterisation.
However, you should go and have a check up to see what's that all about. better safe than sorry.
Go to see doctor dude :| - dont risk your health.
You’d probably be best off consulting a doctor about that rather than random unqualified strangers on Musing.
