I understand. Physically and emotionally that's a lot to live through and process. I think if you could get an accurate diagnosis from someone you trust it might help with the worry. Perhaps that's what your GP was attempting to do by calling it scar tissue from smoking?!? I hope I didn't cause you even more worry and that you can get this resolved and start feeling better!I am sorry if I just gave my life story, I just have to pick myself up and move on and hope,
