Ingrown toenail.....? please help?

First off this is long... So im waiting for my doctor appointment which is on January 3, 2013. Well it hurt so bad so I was trying to get it out and I think I got alot of it out right now because the pressure on the top of my toe is now gone and I saw nail come out with the last color polish I has on them however there is still a pressure on the lower part so does that mean that there is still some in there or is it gone and just normal pressure left? Im going to continue soaking it with water and Epsom salt like my doctor told me to while waiting for the specialist but if the pressure doesn't go away on the bottom then should I just wait until my appointment to get it out? And if so do you think because the pressure is on the lower part of the nail now only that they will just take out the whole toenail. Im really nervous because I have never had an ingrown toenail or ingrown nail at all before this one. I don't even know how I got it. Is it possible that it is from my nephew running over my foot with his skateboard and scooter a bunch of times since I babysit him all the time and he did it everytime until I told Him after I found out what was causing my pain that he couldn't play with it by me and I will sit and watch him. I want to be able to tell my doctor why I got it and idk how because I have always taken care of my nails the way they are supposed to be taken to prevent stuff like this. Sorry this post is so long.
