@Josephine So you're doing therapy/rehab for both foot conditions? Injections? Surgery? Aren't you a nurse? How do your foot problems affect your job? Can you, or should you, do any kind of weightlifting exercise where you are generating force through your feet? How bad is your elbow? Any rehab for that? I'll wait to hear back from you but my first reaction is to get your feet healed up before having you do any leg press, squat, deadlift or any other exercise where you generate force through your feet. Don't know how well equipped your gym is but you could do leg extensions and curls, hip abduction and adduction and back extension. As for your elbow; have you figured out what upper body exercises you can do that don't bother your elbow too much? Since you're a medical professional I assume you're doing your physical therapy. Let me know what you think and tell me whatever else you think I should know. I hope I've been helpful.

@Josephine Any improvement in your symptoms with what you've been doing? Is there any possibility of a different job assignment at least temporarily until you heal up?

@Josephine Ok, I guess this is what we have to work with but if I were you I would at least entertain the possibility of a different job, still in your current field, where you are on your feet less. Since you work in medicine I assume you know all your options with your foot problems? Seen a podiatrist? If you want you could tell me what kind of lower body exercise machines are at your gym. I mentioned a few in a previous comment.
