| I would guess two days rules out psychological...man people after irritating something feel the affects for a while and won't let it go, such as having had something in your eye and you keep rubbing your eyes. It's also possible, depending how far down you feel this, that it went down the wrong pipe. So, no matter how much food or water you drink, you won't be able to get rid of it. Try getting something to numb your throat. You can find it at CVS or whatever pharmacy store near you (as long as you aren't allergic).
If that doesn't work, consult a doctor.
P.S. Stop biting your finger nails.
