I've been experiencing pain in my right lung on and off for about 18 months, more off than on (seem to go through long phases OK and then it comes back for a couple of weeks). Sometimes I feel it in the back, sometimes the side, sometimes the bottom, and sometimes I have the strangest feeling that could almost be described as an itch right in the middle. I don't have a cough, don't seem to be having any problems breathing - basically it's just the pain.
I did have a chest x-ray a few months ago as part of investigations in to something else completely unrelated, they never told me the results of it - which I assumed at the time meant there was nothing abnormal.
I'm an ex-smoker (gave up about 5 years ago) so the first thing I think to myself is cancer. I know, I should go to the doctor, think I am avoiding it as I'm terrified.
