my father is 75 and for at least the last 5 years he has been having difficulty with his feet. He has had multiple testing including mri. They say he has a pinch nerve. He can t feel his feet and part of his legs. His has fallen many times now. They just don t give a very good dignostic. He has started the testing over by having 2 mri this week. Could this be something else or if it is a pinch nerve can they not do something about this?
