How well can neural therapy help with fibromyalgia?

Sometimes quite well: Neural therapy will not necessarily help everyone with fibromyalgia, but if someone has scar tissue creating "interference fields" it may be extremely helpful in reducing pain and improving function. Like many alternative therapies, there is little research demonstrating its effectiveness, but it is very safe and I have seen many patients have remarkable benefit from neural therapy.

Unclear: I think that in order for any of us to give you an accurate answer you should re-sumit your question and be more specific about "neural treatment".

Unusual: Neural therapy with procaine injections into areas of scar, or oral structures, is a rare treatment, occasionally helpful after surgery. Fibromyalgia is rare in someone your age. It should be treated with exercise prescription, management of sleep and depression and bowel complaints, and prohibition of smoking. If your are otherwise healthy, but suffering widespread muscle pain, seek testing.
