Idea: trigger point massage in the bathtub

I've recently discovered trigger point massage. The basic idea is finding painful points on your muscles and applying deep pressure which is initially quite painful, but quickly reduces your overall level of pain in that area. This page has a neat trick, which I will try as soon as I have a bigger bathtub: take a rubber ball into the bathtub and combine the relaxing power of heat with the effects of trigger point massage.
