Thank you for your responses everyone.
I saw a doctor yesterday that works with my GP. She hasn't seen my chest before but I had a comparison photo from Sunday till then and the indentation appears to have indented more in 2 1/2 days.
She said the thing that that reassures her a little bit is that my pain isn't too bad as people with bone cancer apparently have really bad pain. Mine is intermittent tugging medium level pain.
Inam having an an X-ray today so hopefully that will give an answer.
Again, thank you all for your support. Xx
