After reading your post this morning Tanya, I'm thinking that it's possible that it's something like pneumonia or pleurisy, although as Nat said, it's very difficult to diagnose from a post

I would go and get checked out today for sure, if it's either of those things you want to get started on treatment right away.

And just a note, the first time I had pneumonia, it didn't show on the x-ray for days (which I know can happen), so everyone was convinced that I had pleurisy, and gave me horrible tablets that made me incredibly sick. By the time the proper diagnosis was made (days later after repeat x-rays), I was in agony. I slept sitting up on the couch for over a week, it was just way too painful to lie down. I didn't have a cough with it at all, and I hadn't been unwell with anything else. The next time I had it, I knew straight away what the pain was, and the Dr I saw really didn't believe that I had pneumonia, but I insisted on a chest x-ray, and lo and behold, there it was!

So the moral of the long (winded!) story is, that if they can't tell you what is wrong, and the pain is getting worse, just keep going back until you get an answer!

Good luck hun, let us know how you're going
