What Could Restricted Feeling In Chest, Blocked Nostril While Having Tonsil Stones Indicate?

Hello, I have been having problems with my breathing for a year now. i feel like my airways and chest is being restricted, and when I breath naturally it feels like the soft tissues in my nose or throat are touching and it makes a flapping/snoring noise which cuts my airways off. Feels like I m trying to breathe in air but there s something blocking my airways. I have to take short deep breathes to stop that happening, which doesn t feel natural. I also get a feeling that the soft tissues in my throat and nose is swollen, sometimes my left nostril is blocked and nasally. This also affects my voice (makes me sound ill and hoarsey). I also get tonsil stones, sore throats and throat infections frequently. I have been to see my GP, tried nasal sprays, anti biotics, nose drops etc it doesn t help. Also been to see ENT doctor and he said he can t see any lumps or anything but he did say I have acid reflux and gave me oemprozole which didn t help. Problem still exists! Please help me
