I have been having problems off and on (mostly on)with my feet,ankles and now calves swelling and are red (people ask if i'm sunburned). They also are painful when i walk or they are touched. My Dr. does't seem to know what the problem is and does'nt seem too concerned. He has'nt seen them at there worst.Has anyone had any problems like this? I've tried doing some research but theres not a lot of info about the problem as it relates to lung cancer. Theres a lot of possible causes though.Any help or thoughts would be appreciated. I see my Dr. on thur. and am going to insist we get to the bottom of this, because something is not right. thanks all.
