My father is 79 yrs old, about six weeks ago he started with aches over his body, he thought it was the flu, now he is not walking very well, back, legs and arms ache, arms are numb, last week he fell at a gas station and just walking down the sidewalk. He is also very tired,they have ruled out stroke, only after the PT person said he needed to be checked for that, before this his doctors were not taking him too seriously. I m just trying to look symptoms up, he had an MRI last Friday. He also is dropping things.
