As I was diagnosed originally with Fibromyalga, which when I realised didn't fit all of my symptoms & I continued to ask my GP for help, resulting in an additional " Severe M.E./ CFS" diagnosis too - as the years have gone by, all 11 of them
I have continued to collect a string of diagnosis, such as chronic migraine.
More recently, due to my DD being diagnosed with EDS Hypermobility type last November, things have changed - my diagnosis has changed, FMS being a symptom of my true Ehlers Danlos diagnosis.
I'm not the only person I know, whose diagnosis of Fibromyalgia &/or M.E. has turned out to be wrong & the real diagnosis be EDS, which has opened up more understanding & better treatment options, hence why I am sharing this video here, as I've found it to be the most comprehensive & informative I've seen to date & if it helps one person get a true diagnosis & help, then it's would be worthwhile.
My DM was diagnosed just before she died, having lived the later half of her life with an M.S. - turns out EDS actually fit her symptoms FAR better.
I should also add, that I have never considered any of us to be particularly flexible, but realise now that we just didn't notice, as it wasnt extreme & was our "normal" , besides I'm not flexible at all these days, but DD & I passed the tests easily, my DM too retrospectively.
