Dear Linda P.
I am sorry to hear of your dad's cancer, but it looks like it is responding well to treatment and that he has a good prognosis. I have advanced small cell lung cancer that had already spread to my arm and liver at diagnosis three years ago - after going through numerous chemotherapies over this time, my legs have weakened progressively. I believe it is peripheral neuropathy. I have experienced numbness in the feet and tingling in the entire legs only when I walk a longer distance than usual. I try to get some walking in everyday, though it is not far, because that seems to strengthen the legs a little. The weakness and aching in the legs is always evident. There are a variety of symptoms, but you don't have to experience all of them - leg muscle weakness is definitely one of them. Sincerely, LaVerne C.
