I would say the one big difference is there are tests that can prove you have MS, but there is no test that proves you have fibro. The MRI's and CT scans come back normal, as well as, blood work. So fibro is by default, a possibility when all tests are normal. But I can see you trying to come up with the latter MS, when some symptoms are quite like MS. I have gone through periods where I was too weak to get out of bed and my balance was off resulting in falls. The brain fog and fatigue, coupled with other vague symptoms can mimic more serious diseases and worry us to no end. If you continue to follow up with a doctor who runs tests as needed, should there be another disease it will be found someday.
