I would ask your doctor for a Therapy reccommendation. Let the professionals provide you with strengthening excercises as you recuperate. Tell them your concern and I am sure they can assist you in an excercise program that you will be able to tolerate. I have been sedentary with a Meniscus Tear and Arthritis. I go to Therapy 3 days a week and it has helped.

Firstly, staying under 1,000 is more detrimental than helpful to anyone. I know I sound like one of those psychos, yelling EAT SMALL MEALS THROUGHOUT THE DAY!!!! But you really shouldn't be afraid of eating.

what about water aerobics?

Can you do any chair excerises, not sure you can but might be something to look into. I hope you start to get feeling better

Know how you feel, I have a broken foot and am in a boot. I have 3 weeks to go. I really have no advise except to hang in like I am and know it will be over and we can return to our normal lives. Good luck!
