In my opinion Fibromyalgia does get worse over time. Here is the thing, this is a disorder that up until 35 years ago was considered a psychological problem with no physiological basis. Then our expert medical professionals decided maybe there is something to this. I know this because I am a trained Mental Heath counselor with a Master's degree in the field. I was diagnosed about 30 years ago with Fibromyalgia. That is after they tried to tell me before the diagnosis, when I would go with complaints to my doctor, that I needed a good psychiatrist. Then, when they finally decided I had fibromyalgia, they said it could only affect my shoulders and upper body. I disagreed with them and said it affected my whole body and I believed it was neurologically based. Years later, guess what, I was right. Now they know that. So now they are saying it is not progressive. Well I promise you in a few years they will discover it is progressive. I can tell them from personal experience it is. Further more, they will discover that there are many other sensations and symptoms that they say don't exist now but I, from personal experience say there are. For instance, my skin burns and crawls. They can find no reason for this physiologically but I believe it is the fibromyalgia. So when the doctors disagree with you argue your point. They will find out sooner or later.
