Does anybody have cramps in bed prior to getting up? Do you have any tips on how to alleviate this? A problem I experience quite often just after getting up is a sudden onset of muscle spasm around my waist, usually after going downstairs. It feels as if my waist solidifies, making any bending or stretching very painful indeed. This will last for about 1 minute, then will disappear for the rest of the day.
