Fell down a few weeks ago, first time in years. What a shock to take a step, expecting an ankle to be there supporting me, and instead finding myself on my butt on the basement floor! I sprained my foot and opposite knee really bad. Are weak ankles and falling down part of the FM experience? So now, with all the other crappy symptoms, I have to worry about falling down??? Or are weak ankles just another result of not exercising enough...they're weak just like all the other muscles in my body. Actually, I could feel this coming. My ankles have been getting weaker and weaker. When I take a step and one ankle feels like it's "giving out" I usually catch myself and can keep going. But this recent fall was a total surprise and is so depressing! I'm really starting to feel like an invalid. Is my future one of canes and wheelchairs?? This really stinks! I'm only 49 and feel/act like I'm 75!!
