I can answer a bit but am not long enough post op to answer all. I am 3 weeks post op.
how long in hospital - I stayed in 3 nights but my health care insurance had agreed up to 5 nights, but then I had 2 ops at the same time so maybe that increases the length of time needed. They did say I could go after 2 nights but I wanted to stay the extra day cos I didn't feel ok to go home
to get up and about - I was pootling about upstairs like a mad woman locked in the attic the first week, I was coming downstairs and pottering the 2nd week, and the 3rd week I have been out of the house doing stuff but then feel like I have overdone it later that day/the next day. Too much walking isn't good. I am not comfy in the car as a passenger at the mo, so wouldn't consider driving yet.
Pain - in the hospital I was given lots of lovely medicine and felt pretty ok (hooray for morphine). The only painful bit was having the catheter taken out the next day (OMG) and having the packing taken out was odd but not painful, it was more shocking than anything else - how the hell did they get that much up there!?!?!?!. So I am sure it would be painful without drugs but the painkillers mask it and its uncomfortable rather than painful. Ouchy. Not enough to make you want to cry (this is only my experience, obviously everyone is different).
Doing anything you shouldn't will bring some aching and stinging pain, ie bending at the start, and too much walking at 3 weeks. Lifitng anything!!
At home it gets a bit painful so you take the painkillers and its ok. It is painful but NOTHING like having a baby. This toothache I have right now is MUCH more painful than the stitches etc.
But... there is always a but... having a poo after getting home OMG it was like having a baby I nearly died of shock. I could have avoided that by not taking the codeine etc, but eating more veggie/fruity/whatever makes poo soft kind of things. That did hurt but the rest of it has been ok and I think if you are careful with your food/supplements/meds you can avoid that.
TBH its more annoying than painful at this stage, I just want to rip the stitches out cos they are getting on my nerves. For me now the TVT tape aches when I overdo it, and the stitches sting when I wipe my bum.
Hope that helps. It sounds to me like your idea of the pain is lots lots more than my experience of the pain.
