Hi! It's normal to think the worst but if you did have lung  cancer rest assured it would have shown as a shadow on the x- ray! It is highly unlikely to have lung cancer at your age. I think 90% are over 60. Do go back to the doctors but I wouldn't be worried about cancer. It could be a whole range of things, from stress to nerve damage from coughing, if you have damaged a nerve in your back from coughing this can affect your legs and back and shoulders, I'm no doctor but this could be anything. I would definitely get checked again but try not to worry! Good luck xxx

To get so stressed about cancer is something that seems so bizarre to me, I'm not being unkind but when an x Ray has said it's clear, your doctor has also tried to explain  and reassure you that our bodies take time to recover from colds ect. that you still think the worse.  My husband had none of your problems, just a cough and yet he was diagnosed with advanced lung cancer after an x Ray showed a large shadow on his lung, so your x Ray is clear, tumours show up on an x Ray, that's why they do them.  So listen to what the experts have told you and everything should slowly return to normal.  Good luck, Carol 

Lung cancers can be missed by x-rays though. There's a statistic which says x-rays can miss up to 23% of patients with the Lung cancer disease. Sure, i know that's a small percentage, but it proves that there is a chance someone could have lung cancer despite being told that they are clear of it by a chest X-ray.

As my husband has lung cancer we have not looked up statistics but if you keep looking at these sites you will convince yourself that you are ill, regardless of what anyone on here says. .
