This question is on behalf of a co-worker who has had tendonitis in one ankle for almost a year. She's done physical therapy, exercises, etc. but it's been kind of hard to heal 100% since it's really not practical to stay off one's feet for an extended period of time. As she tells me, it comes and goes...some days are ok, but if she's on her feet a long time the pain comes back. Are there any supplements which may help along the healing process? Glucosamine? Recently I've heard that silica may help for inflammation, is this accurate?
