sorry to hear your surgery didnt go as planned. it was what i was dreading myself.
fortunately for me although my liver was inflamed and my gall bladder was, well, yuk! apart from having a bleed on my liver they managed to do it all keyhole. it is a huge improvement to 'being cut'
sympathies with your wound. i have a laporotomy scar top of abdomen straigh down.
it will heal and become less sore
do take it easy if you go back to work, dont overdo it
