Dear Panicmerchant,
I'm sorry to hear that you've been in so much pain. There is a lot of uncertainty associated with this wisdom tooth removal - first, you aren't sure if the dentist can get it out, and second, you don't even know if that's the cause of your symptoms .
How about looking at it this way? You've already said this may be a good thing since you're in a lot of pain. The dentist has already confirmed that it's growing into your jaw, which already means that removing it may be a good idea. Even if this removal doesn't solve your pain problem, you'd have taken care of a potential future problem arising from this tooth. In the best case, your pain problem will disappear entirely. There's nothing to lose in getting that tooth removed.
You've also mentioned the dentist may not be able to get the tooth out. Unfortunately there's no way around that. If it comes to it, then worry about it then. In all honestly, if the dentist was sure there's no way she could get it out, she'd have suggested going to the hospital directly. The fact that she asked you come in tomorrow suggests there is a possibility she may be able to do it herself. So just hang in there (easier said than done, I know). But at least tomorrow, you'll get some answer to your problem - regardless of whether it's having your pain issue resolved, or preparing yourself to go to the hospital. It'll be better than being in a state of uncertainty.
Take care,
M
