Hi John,
Sorry you are having problems. Your symptoms could be caused by Lyme Disease. I also had fatigue problems and weakness in my legs that would come and go in the beginning years. Hot water baths stir up the lyme bacterias making one feel worse and even more fatigued.
Most people don't even know they were bit by a tick because ticks have a "numbing agent" and less than 50% of people get a rash of any type.
I suggest asking your doctor to send your blood to www.IgeneX.com or have the QRiBb test done at:

I hope you feel better,
Denise
