Ahhh...does that bring back memories.
I had an inguinal hernia repair in 1988.
I remember returning to teaching very soon after. Big Brave Man.
I thought I was doing okay. I couldn;t move too much, so for once I sat behind the desk and taught.
It was fine untill the end of the period and I tried to stand up to leave. I think it took 10 minutes to get from sitting to standing!!
Eventually, it took 3 weeks, things got better!
