I am 34 yr old male. Left nasal passage feels blocked almost all the time. Lying on right side while sleeping gives immediate relief. Also, otrivin/ mucoris drops also provide temporary relief. Probe check did not reveal anything. Minor middle bone deviation which in ent' s opinion was not the cause. Problem was attributed to allergy leading to sinus inflammation. However, I doubt it as the problem is perennial in all conditions and has been so for many years. Request advice.
