Welcome to NT!
I'm so sorry you are dealing with all of these symptoms and not getting any answers. I know how frustrating this can be.
At first in reading your post, I wondered if anyone had mentioned 'Fibromyalgia' to you. Unexplained pain can lead to many trails of searching for answers. I made the mistake of trying to find answers via the internet and ended up convinced I had 40 terminal diseases!!
There are many forums here that I'm sure you'll find helpful. Answers might not come right away, but as you gain support from others, you'll see that you are not alone in your struggles. People here are friendly and caring. It's a very down-to-earth atmosphere, so make yourself at home.
Friends are on the way!
Caring,
Rae
