The best way to take natural remedies for inflammation and pain is by following the guidelines on the label. These guidelines are often the minimal doses and therefore for acute conditions the doses can be increased, sometimes doubled or tripled. However, in high doses even natural substances can become toxic in the body. In all cases, it is necessary to use caution and to take supplements and medications as directed on the bottle or as suggested by a professional healthcare provider.
Also, many painful factors in neck, back and muscle pain are deep inside the body — probably much deeper than Voltaren® Gel can “reach.” For instance, if your low back pain is coming from the facet joints — small joints deep in the spine, under a thick layer of muscle — chances are that a topical treatment simply doesn’t stand a chance of having an effect.
However, it probably does not work well for deeper tissues in most cases. For instance, there’s evidence that it doesn’t work at all for the muscle soreness that follows unfamiliar exercise intensity,7 probably because it can’t be absorbed far enough into thick muscle tissue — but oral NSAIDs do have a modest effect on that kind of pain89 (one of the only things that does).
I’m not saying NSAIDs are useless. They have their place. If you’re recovering from surgery or a major injury, traditional over-the-counter pain relievers are good for controlling inflammation, swelling, and pain, but NSAIDs are far too powerful for over-the-counter, everyday use. Unlike a lot of natural pain relievers, NSAIDs also don’t address the cause of inflammation or pain; they just mask the symptoms.
