i get the odd toe thing. only when i'm in water though, and only very rarely - it's like two of my little toes are magnetized and get stuck together and tugged down, and it hurts hooorribly. >w< hard to explain...
the only other odd "cramp" i've had (i thought that's what it was at the time) was one in my lower hip/side that was so painful it made me kneel down on the ground and get all dizzy/sweaty.
turned out that one was a kidney stone. ^^;
