Hi Min
Yes I too drag my feet. I am forced to walk in short steps because in a normal stride my legs wobble. Picture Monty Python ministry of funny walks. I was thoroughly investigated for MS after my viral onset CFS? illness began 14 yrs ago. Initially they talked about some weird form of epilepsy. Then they said myoclonus (lightning jerks in muscle). But when all the conductivity tests MRI's LP's came back 'normal' they dropped me in the CFS waste basket. I, like you, use a wheelchair for distances. For two reasons. I slow to a pace that means it takes me a ridiculous length of time to cover a short distance - therefore it is not practical for me to walk. But also because of the PEM, which hits up to 48 hours after exertion. Do you walk any better in warm weather? I can walk further (and sometimes in a normal gait with longer stride) in really hot conditions...and yet, almost in an instant I will lose 'it' and stagger around like a ten pint drunk (speech is slurred - severe difficulty with language). I still see my infectious diseases consultant twice a year, but I don't even bother asking about any further investigation. They did all the standard stuff and I heard 'don't worry, we'll get to the bottom of this' so many times. But they didn't get to the bottom of it. I would say atypical MS. I doubt the neurologists would. I imagine there is an overlap with CFS/ME and MS. About a year before viral onset I got my first sign all was not right. Lost use of legs for about an hour, virtually falling to floor with every step - this was after walking about 200 yards normally. Weirdest thing. I tried to rationalise about it at the time. Thought maybe a trapped nerve. Ha! Thought wrong obviously.
Anyone else with unusual gait, neurological type symptoms please share. I sometimes think I am only person to have these specific problems with CFS diagnosis. It only goes to show that CFS diagnosis is a complete nonsense, unless you are Psyche doctor who believes if all your tests are 'normal' then it has to be all in your head.
