The bike can get without my orthotics reacurrance my faciatis?

this was a question posted by my friend

I have a torn plantar faciatis. I believe it is 2 ctmtr. I have been in pain for almost a year. Before I was given an MRI, I was first given orthotics that did nothing to help my heel pain. As the months passed, my heel along with my whole foot at the side became more painful. I finally visted another doctor in January and was put in a day cast for three weeks. That did not ease my pain. Then I went for amn MRI on March 15, 2005. That is when the test came back that I had a tear in my plantar faciatis. I have been in a cast for two and half months. I am so tired of sitting doing nothing. Every two weeks I have had the cast taken off and a new one replaced. This week the doctor decided to do another MRI and now it shows I still have the tear plus I have a sprained ankle. HELP!!!! He has now put me in a boot to wear this week until I see him again next week. I need some advise. If you have a torn plantar faciatis, what else can be done besides what I have already done? I am so sick of not being able to do anything, so he asked for help, guess what i replied
