Three times now, I have had cramp in my thighs, and have found this pain to be almost unbearable. I'm usually a stoic--had three babies without so much as a whimper--but this pain made me scream and left me shaking, and my face was literally grey and covered in drops of icy sweat. I'm becoming frightened of going to bed in case it happens again. I get a lot of cramp at night, being woken up by it two or three times most nights, but I can cope with that by walking around for a few minutes, but I can't seem to relieve the thigh cramp at all--tried doubling over, stretching, massage, all to no effect. Any suggestions PLEASE.
