It's amazing, though, how so many doctors still don't seem to know what it is or believe in it. I can understand why the average person might not have heard much about it, but I'm beginning to think the condition is more widespread than we realize. I guess it's because so many of the symptoms are the same as other conditions. But some people feel like you can't have more than one thing wrong with you at a time, like if you have pain in your neck, you can't have it in your ankle or elbow at the same time, so it's very hard to explain.
