yep...I used to get them often. Hubby (the sweetheart) used to have to rub and rub, til they subsided, along with a heating pad. Horrible pain. I used to hate to go to bed, because I knew what I would wake to after a couple of hours.
I haven't had them for ages now...(knocking on wood)
Hope you find relief soon.
Cheers,
Steph
