Patient :Hi since last Wednesday I have had a pain in my right side of back just below the bottom of the rib cage. I went to the doctors and he felt my tummy and listened to my breathing and said it was a lung infection and gave Antibiotics but I still have the pain. I am really scared as everything on the internet States lung cancer. I also have had a cold for about 2 months that I can't seem to shift which worries me. Today I have also started to get pain in the back of my knee left leg don't know if it's separate or something to do with the pain in my back. Please help I'm really worried
