thank you all so much for your feedback. i will always be interested in more help. my mother suffers from the cramps not only in her feet, but all the way up her leg, groin and side. she cannot hold still during these episodes and wants deep massage. i worry that some of the positions, stretches, and ways she wants others to pull on her limbs will hurt her in other ways. the cramping comes on so suddenly, she seems to be both frozen and tightened up all at once.
