Hi @Mic80, it is very variable. I was able to stand straight after 5 days but by then my back was extremely uncomfortable so it was more I had to stand up. I was walking daily after that but initially took it very slow & improved gradually & back at the gym & working in 4 weeks. The tightness lasted for months & I found by the end of the day it was worse & extremely uncomfortable probably from eating & tummy expanding. You are in the very early stages but it might be worth seeing a physio to get you on the right track. Do you have a follow up soon with the surgeon?
