You know that smelly menthol rub you can buy in little tubs at the store for muscle aches? It has like %5 menthol and its in a gel. It works pretty well for me - for my leg cramps at night - so i go through it SO fast.. is there any way for me to concoct my own version of the gel at home that would work just as well? I know with Fibro with have to be CREATIVE and THRIFTY, so thats what i am trying to do. Ideas?
