Hi Don and Mrs. Don,
I'm so sorry you have been so sick. I know a person can get deathly ill from parasites. I have a good friend that is still sick from something she got in Central America. She now has Lupus. I just happened to read about a rare disease called Behcet Disease.
www.american behcet disease association.com Also I know Lyme Disease is a very difficult disorder to diagnose. Were you in the 'woods' You can get a tick bite in the woods or off a deer etc. Hope you get answers. Take care, loretta
