cramps when I lie down

Amsay84

A few weeks ago I started having what feel like menstrual cramps when I lie down.  Sometimes, just from lying on the couch for a short while. Mostly it happens in the middle of the night, after I've been lying down for hours. It wakes me up and is very difficult to fall back to sleep. I never feel pain when standing or sitting up. Has anyone else had something similar happen? Anything to help?  (I'm sure I could take Tylenol, but I don't want to get in the habit of taking it every night.)
