Pennies, that op. does sound daunting. hth but a friend had reconstruction in early January. Not sure exactly which version she had (can ask if you want), but she's been amazed not to feel more debilitated by it all. She's really delighted with the results too. Your new job sounds good - TA's at my DS's school are all fab and have a great time with the kids. Figgy's a TA too I think.
Lime, what have they said about your toes? Do they think you'll get the sensation back again? Amber's having all sorts of problems that sound similar. On ribs, I'd vote for canceritis too. I really do get how worrying it all is, as I've had a CT for similar sounding pain and even though it came back totally clear, I still anxt about it. 
I have a theory about mine that it's a combination of my implant/ scar tissue pressing down and also low level IBS which bloats my stomach, so pushes everything up into my ribs. Totally unscientific, but it seems to fit. My Onc told me nerve endings can jangle too from the surgery, so it could be that too.
Still on a rib ramble, but slight tangent, as I was wondering if anyone else has found they forgot how to breathe through all this nonsense? I've noticed as I try to get fitter that I can't take deep breaths at all. I've had to really work on yoga type exercises to release it all. Lots better now, but it's made me realise how incredibly wound up I've been. Nearly two years now since diagnosis too, so it's been a while..
Ramble over, honest. Night all.
