Kat, Are you one of those people who has to know the end of the movie before watching it?!
I've gone in many times with symptoms that aren't necessarily clear. That's why doctors went through 8+ years of schooling! They can often come to conclusions that we can't.
You aren't on Pred, right? Your symptoms also remind me of someone with lupus or Addison's disease. Or lots of other things! Be on the watch for any other symptoms.
I hope they can figure out what is going on!
