I know you've posted here before...but I'm sorry that I don't remember your whole story (I've got memory issues to begin with).... From what you wrote here, though, I want to just say a couple of quick things.
First - if you are experiencing pain, you have pain. Nobody (not even your mom) can say "it's in your head". I'm sorry, I have boys that aren't far off from your age - and I can't imagine saying that to them (but maybe that's because I understand pain issues). So, please try hard not to let anyone convince you that it's in your head. You know your body and I believe you know when something is "not right".
What does your rheumy say about everything?
Hmmmm, I think sending you to a neurologist is an interesting decision (just my opinion!). I've seen a neuro in the past - but that was for my headaches and so forth. That's usually not the next step in determining the root of your pain issues.
What about seeing an internist, or better yet - a Pain Management doctor. Not only for treatment, but diagnostic purposes. Trigger point injections are great - IF they are working. There are other muscle relaxers. There are other nerve/pain medications. There are other means of treatments.
I guess my best advice would be to somehow find a way to get your mom on board w/ all of this - is that at all possible?? Sit her down and explain how much this is impacting your life. You are too young to be dealing w/ all of this - and not trying to get it treated effectively. I'm all for "all natural" remedies - again, if they work. Would she let you see a Pain Management doctor? (I'm assuming you are still on her health insurance and that's the reason for needing to run this all through her). Try to get her to see that you want to try to get ahold of these issues so that you can start your life out feeling good - w/out such severe pain.
I'll end this though, with what I said at the top. Pain is real....please don't let anyone tell you it's in your head. I hope you are able to find a solution that works for you :( Please keep us updated on things and what you decide to do.
Take care of yourself, hon. --Tina
