Yesterday I ripped my fingernail in half, but its still connected. I don't want to take it off cause it hurts, BAD! Also I did try but it won't come off. I want to know do I go to doctor or just clean it, and if I just clean it will it heal and do have to take the one part of the nail?

The best thing to do is to go to a clinic and get them to clean it up, remove anything that needs removing, and properly bandage it up. This is the optimal and the best solution.

If that isn't feasible than if you clean it up, apply antibacterial ointment, keep it clean and dry you should also be fine. Don't try to remove anything, just bandage it up and allow it to heal as it will. Chances are it will fall off and the rest of your nail will grow in. The important thing to not is that the nail bed that is now uncovered will be a ripe breeding group for an infection. Keep good care of it and don't let it get infected.
