Re: Could this be Lyme's Disease?
Your symptoms could be related to Lyme, my illness started off with some of the symptoms you mention, although many other illness and diseases can also cause what you are experiencing.
The only thing I would say is that if you have had extensive testing already to rule out most things, then I would seriously consider being evaluated for Lyme as it can mimic so many other illnesses.
You would need to seek out an LLMD as unfortunately mainstream doctors know very little about Lyme, and the tests are extremely unreliable.
Lyme can often be a clinical diagnosis based on symptoms and history, and not on tests alone! It's a very complex illness to treat and only a doctor who is very experienced will be able to help you.
Maybe you could send your blood work off to Iginex which is a more reliable lab, whilst you seek out an LLMD.
