Hello , one side nose block and it switches after every few hour , some time both nose block, and also stickiness in throat . Due to which facing breathing difficulties. I have these symptom from last 1 year when I was in my native (costal area) 2 month back I moved to Bangalore and I felt better in that 2 month . 75% of my symptom was not there in that 2 month . But 3 days back I came back to my native (costal area) and again I m facing same breathing issue , nose block and sticky throat . if I try to blow from nose air won't come out and I can feel air pressure inside my ear . what might be the reason ? All my reports are normal including nasal scanning .
