Here is an update for those of you that wanted it.
The MRI turned out fine. Flip side is they don't know what is wrong. No idea at all.
While I am thankful that all the tests came back negative, I'm really frustrated, too. I guess I'm just supposed to live like this.
I know so many of you have things much worse to deal with so I don't want to make a big deal of this or complain. This on top of the rest of things in my life, is really, really bringing me down.
So, thanks for caring and asking about me, I appreciate it.
