Kathy - reading your last post - you are lucky to be able to use the Voltaren gel, as that is also an NSAID, just a topical one. I have a friend so sensitive to them that she can't even use the gels. I'm working (with some success!) on making my own product at the moment...I've been making soaps, balms, moisturisers and stuff for a few years now and decided to try a 'pain balm' using mainly arnica and menthol. I haven't got it quite right yet - the consistency is too greasy to use it easily - but it sure does seem to help with muscle pain
