Am I the only one that does not have flares but daily ongoing pain?

Am I the only one that doesn't get flares but instead has daily chronic pain in my body? And daily symptoms. In about a 50-day time frame I seem to cycle through my symptoms and pain levels. That will then repeat. I will experience the same pattern of symptoms throughout that time. There will be anywhere from 2 weeks to one month of moderate daily to sometimes severe pain in the same areas, although it can be one leg one time and the other leg the next and then switch. Or be both at the same time. And then about one week or so of a more milder pain. But still there daily. Symptoms such as insomnia will always be there and some of the other Fibro symptoms are every day while some of the other stranger symptoms will cycle throughout that same time period. And it will go on and on like this, never stopping.
Now that I am older, I have other complications such as uncontrolled Diabetes 2 and Degenerative Disk Disease in my back to give two examples, but they have nothing to do with my Fibromyalgia and that can make things more confusing and harder, but I have learned to tell the difference for the most part.
I was diagnosed in 2001 when I was only 25 years old. I was diagnosed by two Fibro specialists. As well as Chronic Fatigue Syndrome. And it has always been the same for me. No flares just daily pain and symptoms with only the intensity changing. Or is that what a flare is? But I use the term cycle because that is what it does. It is predictable. Flares I thought were not. And I read or so it seemed to me that when not in a flare people with Fibro feel normal or almost normal. Every day I feel pain it is just where it is located exactly that can be a little different but not always and the coming of some symptoms while other symptoms move on just to repeat the same process and pattern and in the same time frames.
All the research I have done through the years if it is in forums with people or information read on the internet, or in books, by doctors, or things I here, flares are always being talked about. This has always made me feel uneasy about my diagnosis and has me wondering sometimes if I don't have something else. At the time of diagnosis though I was perfectly healthy otherwise. And like I said I was diagnosed by specialists. And not just any specialist but one of the leading Fibro Specialists in Los Angeles names Dr. Silverman who worked at the Mayo Hospital and clinic (still might) and has written books on the subject. As well as another Fibro Specialist and back surgeon that also has a lot of stuff written on the topic and is well known in his area. Can anyone here relate to or experience this same kind of cycling behavior? Do you also not have flares but daily everyday pain? I have been like this for 23 years.
