Hi, Nancy.
I hope the PEG placement goes well. You'll just be sore in the tummy for a few days and turning in bed/coughing might hurt a bit. Brace your tummy with a firm throw pillow if you are going to cough or sneeze and that will help with the pain.
Your throat shouldn't be any worse due to the procedure. They shouldn't have to intubate you for this placement, just IV sedation. You will most likely be able to go to rads on MOnday if you truly feel up to it. I understand that you want to "git 'er done"!
Best wishes for tomorrow! BTW, my doctor is Daniel Deschler, MD...love him to pieces!
xoxo,
Kerri
