So here's an update - I have managed to pass a stool - okay, okay, i'll say it! - I have manged to do a poo - and I feel so much better! The first one was quite dramatic, needed multiple flushes!
Still swollen around the operation site(s), and very very swollen scrotum, but not painful, just uncomfortable. I am walking (waddling) around the house, and even walked outside the house for 100 yards or so.
I have a follow-up at the hospital this week, and a date for an appointment with the consultant to discuss histology results in about 4 weeks time
Thank you all for your helpful comments.
