thank u all for the advise!
as soon as i opened the tube to flush it, alot of air came out. he actually said that relieved some of the pain--who would have thought.
he said today it is still painful, but about 1/2 as much as yesterday.

his shoulders were also bothering him yesterday which i read was linked to this proceedure. today they are fine.

he has a very high tolerance for pain so when he was screaming in agony last night, i knew he was in a tremendous amount of pain. he was screaming at me saying "why did i listen to you and get this thing". even though the MO instisted but i also pushed him, telling him better safe than sorry.

today is a new day, he is doing better. he missed his IMRT yesterday and today but will restart tomorrow along with chemo.
