And welcome to this wonderful Family of friends with Fibromyalgia. It sounds like you have quiet a severe case of dizziness. I'm so sorry you have to deal with this. I can only imagine how frustrating it must be. But don't give up! We'll be right here beside you whenever you need us.
I'm another one who needs rubber bumpers. I've started labeling the bruises on my body each day so I remember what I bumped into 'this time'.
But seriously, it's not only frustrating but painful!
I also would suggest looking into Fibro 101 and especially the section on seeking out a university/teaching hospital. Most states have one or more where you can get cutting edge treatment, technology and research. They aren't going to throw up their hands and give up on you. Here's the link to many of these facilities around the world so you don't have to go searching for it. en.wikipedia.org/wiki/List_of_university_hospitals
Even if you have to travel a significant distance I feel it would be worth it if you seem to have run out of options and help locally. Give the nearest one a call, explain what you are dealing with and ask for the name of a doctor or clinic that can help.
Good luck and please keep in touch...
