Cool, I am glad I could be of some help.
Good luck with the forearm graft, I hope it goes well for you.
I am very pleased with the aesthetics, I think they have done a good job.
Also, with the surgery I went for, I was very fortunate that Mr.Christopher was able to do nerve work on me, so I have sensation. However, I do hear the forearm one provides the best sensation!
I don't have any experience with charing cross (I didn't go through them), but obviously have been to Harley street.
As for time off, for your first op, I would guess atleast 4 weeks...? It is heavy duty stuff on the arm, you will be padded up for awhile and will be very sore. But getting the train back home isn't impossible.
As for going to work between ops, definitely you can. They cant want atleast 4 months between each stage anyway, and you will be healed by then
