Thanks for all the well wishes.
I had a pretty quiet night last night and slept for a good 9 hours, on top of sleeping basically all day yesterday.
Hoping the worst is yet again behind me.
Still quite a bit of residual pain and soreness, but nothing compared to what came before.
So I'm gonna take it really easy and lay down on the sofa and get some more sleep after I put up a new magazine from the backlog.
