I do everything I can to get to pain, and I never do. I pump up to full capacity and leave it inflated for a couple of hours and don't feel any pain. At most, a *little discomfort under the tips, but nothing even approaching pain.
I wonder if my 3 months of VED prior to the surgery stretched me out much further than the cylinders ever will. I would get to 7 3/4 in the tube without much trouble, and now I'm 6 5/8" x 5 1/4" fully inflated.
Am I lucky or unlucky? I can't tell. This sounds weird, but I kind of wanted the pain. I've been cycling for less than a week.
EDIT: I didn't want a lot of pain, just a little pain.
