I missed this post! That was during the week I had no internet. :(
Boy do I remember those pains. They were unbearable at times. I used to put my feet up level with my body at nights, and alternate peaking my knees. Sometimes Craig would massage my calves because the Charlie Horses were PAINFUL!!
Congrats on the Grandbaby! Tell her to take it easy. :) Nice warm baths are usually a cure all for me. :)
I experienced it my whole pregnancy....it got worse toward the end of my pregnancy as the baby got bigger. I am not really sure there is anything you can do about it. I just made sure I wasn't standing or walking for too long, as that seemed to aggravate it more. Massaging might help it somewhat. I wish I could answer your question better. The joys of pregnancy!! =)
