This problem started 5years ago when i felt dawn on floor while tooking water to home! when i felt dawn i haven't get injured or serious hurt after taking 10min rest i feel everything is fine but after that 10days i feel weakness in my legs and after sometime i was not able to stand/walk. After consultation with neurologist 3Times MRI scan done 5Blood tests are done 2xra's are done however nothing was out in reports everything is showing normal so why i was not able to walk properly?? just only their guess was may be it's vitamin deficiency of spinal cord from neck!
