I forgot to to mention I have a untreated root canal for like 2 years now. I know that's bad but I waited this long because i haven't felt any pain on my tooth. Maybe this could be a factor to my issue
I don't quite understand what an untreated root canal is. A root canal is a surgical procedure -- either you've gotten one or you haven't. If you're saying you were diagnosed as having a dead nerve that required a root canal but didn't get one, that's odd to me as well because I've had a lot of root canals and when you need one you'll do anything to get one. The pain is intense. The only time this isn't true is when you have a cracked tooth that needs a root canal because it can't be fixed with just a crown, and then you get a crown put on it. But whatever you actually have going on, why would you think a bunch of people of the internet are going to be of any help? You need to see a doctor if you're having all those symptoms -- I mean, you're definitely not describing anything that even remotely resembles lung cancer, but you are describing discomfort that isn't going anywhere. Anxiety can cause you to obsess over things you might not notice otherwise, but anxious people get all the same problems everyone else does. If you think you've got a shoulder problem, it's not going anywhere if you don't find out if you do have one. It could be a little physical therapy will do the trick if that's the case. And if you need a root canal, you either get it or get the tooth pulled -- if it's infected, that infection can spread to adjacent teeth. I get your avoidance -- I do it too because the stress of getting things taken care of often feels worse than the problem, but the problems aren't going anywhere if you don't fix them. I also hope you're seeing a therapist to try to fix this anxiety problem and, given it's gotten to the point you're neglecting your health over it, you might be a person who needs medication. A therapist can help you make that decision. Good luck.
