Good afternoon Emmy
I don't think you can transfer a thread to another area you would have to start again by typing your original message.You are right about the doctors not having experiencd the problems which you and I face. I have said many times that everyone views the cancer problem from the outside up to the moment of diagnosis , that is when you step over a threshold and start to view the problem from the inside.....and the picture is quite different.
The shoulder pain comes as part of the package and can last for quite a while, discuss it the next time you go to the clinic they will give you some exercises and decent pain killers. I seem to remember that I was prescribed a combination of cocodamal and anti inflammatory which worked reasonably well.
Regarding questions you should ask, you are the best judge of that, what are the things which are worrying you? A good plan is to keep a note pad handy and as questions pop up in your mind make a note and take the pad with you to the appointment otherwise you arrive with a mind full of wuestions and as soon as the chap in the white coat turns up your mind goes blank, it is called consulting room amnesia. I still follow this practice ten years on.
