Teri, it is great that acetomenophin works for you. The only time it works for me is post-surgery, when alternated with an NSAID to control post-op pain. For my arthritis, NSAID's work, but I have probably exceeded a reasonable "lifetime limit" many times over in the past 39 years, so I rely on other strategies.
Voltaren or diclofenac gel takes the edge off on bad days, especially alternated with an essential oil roll-on that contains a number of oils with anti-inflammatory properties, and combined with deep breathing, meditation & stretching.
Some day there will be a cure!
