I've had chest pain and tickly cough for a couple of years. Stopped smoking 4 months ago and thought that would cure it. It didn't!! Went to doctor and had chest x-ray which showed 14mm nodule in upper right lung. Got referred for CT scan. Had the CT scan within one week of x-ray and got told yesterday that it's clear no nodule. Don't get me wrong that's great if it's correct but I don't understand how a 14mm nodule could disappear in a week and I still have chest pain and cough. I know nodules can clear up but surely not that size in a week!? Is there a chance my CT scans results got muddled up. Im really worried and would like another chest X ray. Sorry to bother this forum but wasn't sure who else to talk to.
