It feels like there is something stuck in my throat.it comes and goes.and when I swallow my spit that is in my mouth,it taste kind of weird.it usually goes away for a bit when I eat something,but it just comes back.its been going on for a couple of months now.I tried to throw it up,but I couldn't. I couldn't spit it out.I tried coughing it out nothing works, but when I was little I had something wrong with my throat.could it be that,or is it something else?I used to eat paper,I know that's weird, but could it be that also?
