Since I was a child I could remember getting cramps in my neck at random moments. They would last for less than a minute or so then slowly ease back to normal. This persists even up to now but I mostly blew it off. But these past few months I've been subject to involuntarily spasms at night, usually just before I completely fall asleep. Either my whole body would just suddenly jerk hard once, or a limb, hand or foot would spasm involuntarily. I know it's a long shot but I was just wondering if the two conditions may be connected, and if anything major (e.g pinched nerves in the neck/spinal damage) could possibly be amiss. I have no knowledge of experiencing trauma in my body, I've never had an accident or a major operation. I also have never taken drugs which could compromise my health. I would be extremely grateful to anyone who can share any experience or insight.
