They say fibro is not progressive. but the truth is the medical community knows so little about fibromyalgia that anything they say about it now could be disclaimed years from now. fibromyalgia is an umbrella term that covers so many different symptoms and levels of pain and fogginess and everything else that really there's no clear definition of it. They know so little that I take what they say about it with a grain of salt, personally.
that's not to say is IS progressive, either. That's the thing. We don't know.
If your symptoms are getting worse, there may be a reason for that, which is aside from your having fibro. If the worsening is significant, I would recommend getting tested for a few things that it could be, which are progressive. MS, for instance, is known to be progressive. Be good just to rule those things out.
Other than that, as we get older physical problems become harder, and that may also be part of what you are experiencing. Check out the post at the top of the General forum on advice for managing fibromyalgia, and start implementing as many of those things as you can. As time goes by, keeping yourself in the best physical health you can will help it not to get worse. Making sure your diet is healthy and adequate and getting enough exercise and movement are the most important things, along with doing your best to maintain a healthy mental state.
If your lifestyle has become more sedentary than it used to be, that may be causing this. Get out and be as active as you can and eat a very healthy diet and see if anything changes.
Best of luck to you!
