During my pregnancies I had severe cramps in the calves- it was so severe that it woke me up from sleep. The doc said that one possible thing that could alleviate this was adding calcium- so I ate thru 5 tums each day... Also, he said that doing calf stretches just before bed... (and the 2 ways I know are standing on the edge of a step with your heel off the step and leaning forward against the wall with UR heels off the ground.. and both seem really dicey if you have PD..).. When the cramps woke me up, he said to stand up with my fett flat on a cold floor- so I had to run to the bathroom to stand on the lino there- the massage also hurt. abi (whose Dad has PD and is 73/4)
