Hi puppylover: I have never had that surgery, but just wanted to wish you well. It sounds like you are already very organized! Way to go!
I have little to add, but was just thinking that grocery stores and such that have delis would have ready-made sandwiches, salads, etc..(in case you need more ideas re food--sounds like you're all ready, though).
I don't know if they're even still around, but how about
a poncho-type of shirt or sweater? Just did a (2 second) search and a few things came up.
Sorry your fibro is flaring. Mine has been especially mean this winter, so I can relate somewhat. What's up with that? I hope when you have your surgery things will have tamed down.
Keeping you in my prayers and sending you best wishes.
Please keep us posted on your recovery, if you're able (probably very tricky with a sling!). We all wish you well!
