Phew and hooray for you, Gracie. Though am not surprised you bawled your eyes out. I can't imagine the stress that MRI must have caused. Hope you can sort out whatever it is soon, but at least it's not bloody cancer. 
Malt, I think they usually do sentinel node testing first, so they put a dye in to see which way the nodes are working (ie trace where fluid goes), then take the first few to sample. If no cancer in those, there won't be any higher up, so you only get full clearance if the original sample has some cancer iyswim.
worried, it's weird how we're all so different nodes-wise. They managed to take 22 from me (4 had cancer traces), but I was chatting to a woman at my last check up who'd just had her op and they'd only taken 9. Glad your op's so soon, as that's another thing done with. Ask anything you want here.
Lily, have a restful time being home alone. Typhoid?!
Didn't he also get Malaria a while back, or am I remembering wrong??
MAS, hope you're feeling okay today. Not surprising you have your down days, but still, must be irksome. xx
Yay for Betsy and one more Tax 
NotJ, house move sounds mighty stressful. Really hope you hear from the bank soon.
Are you buried in yarn, Trice?? 
Been swimming with DS, off babysitting for a friend later. Hardly rock and roll, but all good. Hope everyone's okay today and having the best of weekends.
