Hello tallulahxoxo: I'm sorry you are struggling.

I have a ruptured disc in my low back & sciatica. (I also have tinnitus.) So I know something about chronic pain. But mine isn't undiagnosed. It's simply not treatable... at least not in any way I'd be willing to submit to.
Are you familiar with PsychCentral's sister website: "NeuroTalk"? There are a lot of members there who are very well informed with regard to all sorts of physical / medical problems. If you're not familiar with NeuroTalk. It might be something to check out.
