Fibromyalgia is a miserable disease to have. It is a chronic pain condition with trigger points throughout the body that people have to live with it, day in and day out. The cause is not clear but it is related to a genetic predisposition and sleep disturbances are a common characteristic. There are many different treatments that get touted for fibromyalgia but none of them are a hundred percent successful many good clinical trials have shown what is effective at helping some people some of the time but no treatment has been shown to be effective for all people with fibromyalgia all the time. This, unfortunately, opens up those with five fibromyalgia to the snake oil salesman who tout the magical curs – this is just a tax on wallets of those who are desperate for a cure for a condition that does not yet have a cure. The best that the treatments can offer is management to keep it under control.
When it comes to the foot, the pain from any foot condition is just worse than what it would normally be and things like planter fasciitis are very common. Podiatrist commonly treat this condition and certainly know that in those with fibromyalgia the pain is much worse.
There is one book that makes the claim that treatment of the foot by podiatry can cure fibromyalgia. This is certainly not the view of mainstream podiatry and there is no evidence that any sort of treatment of the foot can cure fibromyalgia. Obviously those with foot pain and fibromyalgia are going to feel better if the foot pain is treated, but that is something different than claims that are made in this book. The book consists of a large number of logical fallacies to make the arguments and nothing more than anecdotes with no science. Not recommended.
