Any podcast episodes about keeping muscle mass while recovering from injury?

The doctor said it’s probably tendinitis or overuse but didn’t seem to know for sure. I’m hoping PT will help figure it out, but at least the scans and tests seemed to rule out anything super bad. I can walk now and the pain is gone, but I can also tell something is wrong with it.

I talked about it a bit here: I have a sharp pain behind my left knee that is only there when I point my toes up. Any ideas? - #5 by adammeyer
