Daily night around 8-830 I am feeling that my nose is block. I am able to breath but with pressure, I can fell some sputum inside my nose actually Not even a single breath I can feel is complete unless I take a yawn or breath by mouth. I am using otrivin from around 3-4 days. I have bp of 170/110 and I am taking medicine and during nose congestion it's normal around 150/90. Could you please tell what could be the reason.
