Worded better this time; people stretch in bed when they wake up. i do too but its more of an involuntary spasm where i just tense up and cramp and hurt my back. wondering if you ever heard of such a thing and what could be done about it?

Back cramp during stretch is not as common as leg cramp but it does happen and I assume it is more painful than leg cramp. Some suggestions: -do not stay in bed too long - hydration well on the previous day if working in hot weather or sweating a lot - cramp could be precipitated by certain prescription medications (talk to your doctor) - take magnesium supplement 200 mg at dinner time (OTC).
