Forearm massager looks scary, probably works okay
Anyway, this Forearm Pain Relief Massager from Hammacher Schlemmer apparently leverages the magic power of “the Swedish arm massage technique” to roll away “inflamed, stiff extensor and flexor muscles that cause forearm pain.” It looks like it might work, too, although for $50 more than a few of us will probably have to just play through the pain.
