I Am 50 Year Old Woman Who Had Lung Cancer

I am 50 year old woman who had lung cancer last year. It was removed and so far no further cancer. I had a cough which took me to the doctor and he found the cancer. However I still have the cough. I am full and not hungry. There are a lot of foods I do not taste. I do have GERD and take pantoprazole 2x's a day. There are times that it feels like I do not have control of my legs which are weak. I have had nerve tests which show a little delay but nothing to be concerned about. It isn't a muscle issue either or so the doctors have ruled out. Another doctor is going to look in my stomach to see if it is emptying or there is an issue there. So if that is normal where would you suggest I go next?
Thanks,
Angel
