How old are you? How tall are you? How much do you weigh? Any weight change? Can you tell me more about your problem? Do you have any symptoms such as numbness, weakness, tingling sensation in your legs? Does anything make it better or worse? Is it consistent? Is it getting worse? Are you aware of anything which might have triggered it? What is the rrason you were using a cane? Any medical problems? Any surgeries? Any medications including over-the-counter pills and herbs? Any family medical history?
Can you tell me more about the situation when you had falls?
After you started to take primidone, did the double vision, weakness in your arms & chest, fatigue start?
Did you have MRI of the brain? Are you a male or a female? Do you have weakness, numbness, pain in the feet? Did you have your eyes checked by an eye doctor?
That means your feet don't seem to be good to coordinate to walk because you don't have weakness, numbness, pain, or tingling sensation and don't have eye problem. You could have problem in the part of the brain to coordinate the movement of the feet. You should have MRI to detect the cause.
