Tom calm down...

Assuming the worst, it sounds like it may be at a very early stage, which makes it very likely for a positive outcome.

I'm not a Dr, but I can tell you I have been there myself.

I'm not sure why you are having another Xray? Is it to help diagnose the spot?

I think a visit to an ENT to explore all your symptoms would be most pruduent.

You have a lot going on in your life right now, and the changes, stress and worry could all be materializing in these symptoms.

Get it checked out, and then you can celebrate when it's nothing serious!
