I think I will be joining you soon. My back is very, very angry at me and I am self diagnosing it as piriformis syndrome. I go to the doctor Friday.
Are you in a cast or a boot? If you are in a boot can you get in the pool? I trained for the 2012 Princess in the pool "running" in the deep end with a float belt on? Our Y has a crank machine--I am sure there is a more formal term, but it has a seat and you can adjust the resistance and crank our a workout with your arms. It is really hard and I am usually dripping sweat at the end. When I had to be off my foot I was up to 20-30 minutes--10 each direction. Yesterday I did 2 each direction....It is hard!
You can lift weights from a bench and be off your foot. Yesterday I used the bench because my back was hurting so much. You could try chair yoga--which if you google it, it will come up saying it is for seniors, but one thing I read said for those with mobility issues as well.
I am sorry you are having to deal with this.

It is so difficult when you are used to being active. And it is so hard for me to control the emotional eating when I am injured, so I totally get what you are dealing with. I told Mike that if I am sidelined again he is going to have to come get me off the roof.
Hang in there!
