I am so sick of my feet hurting

The foot surgery I had done over the summer on my right foot did nothing long term. I had some relief for a small amount of time, then I had cortisone shots in both feet, and had relief for about 2 weeks. I haven't been back to the foot doctor since Oct. I've just been putting it off. Tuesday I have an appointment after school. I can't live like this any more. I hate walking around all day, I spent an enormous amount on shoes from Foot Solutions right before Christmas hoping that would help. And I wear my orthotics which are terrible. A friend suggested gellins. I had never heard of them before, but saw a commercial for them last night, so i"ll look for them. I am so desperate for relief. I know my next step is a much bigger surgery, where I will not be able to bear weight on my feet for several weeks. And there is no guarantee it will even work. And I doubt I can have both feet done at the same time. UGH, MY FEET HURT!
