What can solve my nose problems?Look description for more details.

Ever since I was young,I have had serious nose blockage and it is like in liquid form,but is like i try to get it all out by like pressing on one side of the nose and exhaling hardly but sometimes it just feels like its block from the inside.My nose also gets block when I am lying down on my bed and my left nose gets block if I lean left and same happens to my right.I am a chinese but don’t trust traditional chinese medicine practitioners but my dad forced my to go,and the guy charged me $250SGD(about$300+USD) and he said he’s gonna get rid of two pieces of meat inside my nose from the inside that is blocking my nose,and I was pain as hell,he used chemicals to burn it out,but a few months have past and I still have the same problems!Any western advice?
