I have a niece with Lyme disease. It took her doctors over 2 years before it was diagnosed as Lyme disease. I've read that a lot of it is due to no standardized testing to identify the disease but that may be over simplifying it a bit. Once they found out what she had, they were able to treat her and she's doing great now. Here are a couple of links that may interest you:

@parus I appreciate your sharing with us a little more about your health situation. We can all become very inward when we have health problems that don't seem easily diagnosed or treated by the medical profession. The process of chipping away at the walls that we have put up around us can be a slow process and it sometimes takes us all time to process new ideas and come up with solutions. For some people, problem solving is very easy and for others of us it takes time. I appreciate your admitting that you need to "chew my cud for a bit" this is probably the best way for you to process all that is going on right now. As you process and think about your health problems, you will undoubtedly come up with some tools for dealing with it - we all tend to do that, but in our own time. Teresa

I was diagnosed with Fibromyalgia in 1992. I have called it the trash can disease for most of those years.

Was diagnosed with Fibro forty years ago. I have been told that there is no cure nor can anything be done for it. I have been in numerous groups to determine if anything can help. I must say, at this point there is nothing I can do to make the pain go away, I am 68 years old and live in East Texas. Now my Rumo Dr has informed me that I never had Fibro and with muscle biopsy I now have inclusive body myositis. Same same. Nothing can be done nor can anything make the pain better. Prednisone is the only help I can get but the side effects are very damaging.
