Hello, I am looking for some advice and support regarding what happens when you have a chest xray. 

I have had very mild vague pain in the left side of my chest and left shoulder blade area for about a year now and I have lost around 4kg in weight within 8 months unintentionally. 

My GP did bloods which all came back clear and she sent me for a chest xray which I went for 10 days ago. 

I'm 46 and a smoker and both my parents passed away from lung cancer which is making me absolutely terrified. 

Could anyone advise me on whether a chest xray result would have already been sent to my doctor by now if anything concerning had shown up? 

I've been googling my symptoms and it's coming up with lung cancer as a possibility. 

The pain I get is only mild and comes in brief episodes, sometimes it feels like a flash of nerve type pain and sometimes it's like a throb, I get it in the side of my left breast and around my armpit into the shoulder blade and sometimes it goes down my arm. 

I am so worried I'm driving myself mad so any advice would be very much appreciated.
