During start of winters and specially in the morning, there is strong sensation in the inner walls of nose somewhere near the nasal bone. It leads to the oozing of transparent viscous fluid and several sneezes at one go. Several years ago, I visited a homoepath and got some relief. But then the problem came back, and since last 3-4 years it is troubling me. To me it seems to be triggered by cold weather with pollution. It does not happen to me when I go to high mountains during trekking, although the weather is much colder there than the plains. Is it sinusitis, though there is no headache experienced when sensation or sneezing happens.
