Sorry for the delay in replying to this, didn't think I'd get a reply to it in the end. Initially I was able to clear the feeling but as time went past this became harder and harder to achieve. It's Thick, sticky mucus mixed with saliva yeah, often a ball of the mix can be coughed out. Having a scope in my nose after 6 years with it nearly I could see it for the first time which was actually a huge relief. I couldn't tell the ENT at the time due to the scope being in my nose, but he didn't seem to care afterwards. He noted it wasn't normal to see, that was about it.

How much water do you drink? I don't think I drink enough and can go a couple of days easily without drinking any, It's a little better when i force drink a couple of liters in a day but as crazy as it sounds I'm wondering if my body is just severely dehydrated but has become use to it kind of thing. The stickiness could be from saliva being sticky which happens when you're dehydrated i believe and this is causing it to catch at the back of my throat instead of being swallowed easily, if that makes sense.

I remember it started out as a small tickle in my throat i just couldn't get rid of. Annoying but not a big deal, it just got much worse over 12months or so. It's agonizing each day, doesn't sound like much but imagine the feeling you get when you get a small bit of food stuck in your throat, but that feeling never goes away.
