feet problems

I am feeling a little discouraged right now because after the last year of working out 4-5 days a week I started having problems with my feet I have been to the foot doctor and started getting cortisone shots in one heal and some medication, it is starting to feel better and I will need some arch supports and some more shots, but then the other foot started bothering me. I love to walk on the treadmill because I can't do the eliptical machine and how the heck can you exercise without your feet! Uggghhhh....I am hopeful that between the shots, medicine and arch supports that I can pass this slump soon, it just gets so frustrating. I am thankful that I have not gained any weight during the last couple of weeks and have maintained but i do have a workout buddy that I feel I have let down. She probably understands because she has had some foot problems too, but I hate not being there. I guess that the important thing to remember is that this is just a set back and I am not giving up I am looking forward to spending the Thanksgiving holiday with my family and plan on only tasting some of the desserts, not chowing down on them. I am grateful to be alive and pretty healthy and that my family and friends are as well. Happy Thanksgiving everyone
