Hi Arthur,
For me i managed to tolerate with standard pain killers, but i found the catheter to be more uncomfortable than the pain from surgery.
I wasn't able to have the spinal that most men have, as they spent 15mins+ trying to get the needle in, but couldn't manage it.
I expected to be in agony the next day after the anaesthetic wore off and the opiates died down, but was ok.
During the day i could tolerate the catheter after taking pain killers and getting into a comfortable position, but trying to tolerate it when getting into bed, with the big bag was not much fun.
Best wishes
Hertsman
