I have nose blockage problem from 4 to 5 days. Alternate nose get blocked. In the sleep 1 or 2 times both the nose get blocked. I have tried using vicks vaporub, nasal spray, taking steam before going bed, using vicks vaporub in steam, basic pranayama everything. But it is not getting better. Now I regularly use hot water for drinking and stopped taking curd, buttermilk and other dairy products. I don't have running nose. For some time when I forceably allow mucus out, both nose will be clear but with in few minutes one of the nose start blocking. What is the solution for this problem ?
