Theresa, sorry that you have no appetite, and that eating is "something to get through". Hope you are getting your proteins in -- coffee or whatever. With your hubby in charge, that helps. Getting the necessary protein is the most important part food-wise (according to everybody in the bariatric group). I've learned sooo much as a support person for our mutual friend -- and from all of you in that group. Hopefully one of these days -- when you're further along in your recuperation -- we can get together somewhere in between our 2 locations in North Carolina.
Meanwhile don't worry about venting, crying, "down times", etc. We've all been there. Everybody here understands -- regardless of where we are individually in this journey. The first couple of months were the worst for me -- trying to sleep between changing positions every few minutes because Magrat (my new right knee) complained yet again, taking pain meds by the clock, icing, elevating, resting,
etc. -- oh yes, and PT (at home and then out-patient).
As for your hand surgery -- if you can have it scheduled for mid-November, you'd still be covered with the deductables. By mid-November you'll be 3-1/2 months post-op. You'll be much better by then. The main reason that I had the shin splint was because of the convention at 3 months post-op. Your hand surgery recovery won't bother your knee recovery surgery.
I really AM doing better with the shin splint. The PT staff where I'm going is wonderful. They ease up when my leg or Magrat complain, and are helping with the cramps and tightness in the calf of my right leg (which still happens sometimes). They use massage, ultrasound, icing, and stretching/strengthening exercises to help loosen things -- but NOT to the point of pain. Uncomfortable is OK, but NOT pain. I'm able to walk MUCH better now. I can do "mall walking" now rather than "mall meandering" (involves slowly walking and sitting down on the mall benches when my leg would "seize"). The mall meandering was what I was doing BEFORE the RTKR. I am SO enjoying being able to walk better.
You'll get there too, dear friend.

It felt fine until the last 2 days, and then got worse after returning home. I'm doing physical therapy again, my ROM was decreased but is gradually improving yet again. My knee (and leg) definitely lets me know when I need to "back off" and sometimes do NO exercises for 2-3 (or more) days.
