For years and years (25+) I would wake in the night and find I was sleeping with all my muscles really rigid - with them all tight. I would have no problem falling asleep. But, I would wake many times in the night, sometimes more than once an hour, even for a few minutes, and be able to go back to sleep. But, after a few minutes asleep, I would be "tight". My Ex used to say it was like sleeping next to a board. So, in the morning I would be so sore. I had a lower back injury from falling down an old canal bed when riding a horse when I was 17, and have suffered from muscle spasms ever since. That accident was when I think I got the FM. Anyway, this "sleeping tight" has become worse through the years. About 3 years ago, I happened to mention it to my family Dr. and she put me on flexeril at night. Wow, what a difference. Wasn't quite enough to really do the trick, but it helped. Was sent to Rhueumy 6 months ago for broken foot pain that would not go away. Rheumy asked about all sorts of things! She was great. Rheumy asked about sleep and I told her how when I wake in the night, I am all tense and rigid. I think it was one of the things that led her to the FM diagnosis. Now I take a lot more Flexeril, and rarely wake in the night, and when I do, I am not tight at all. Massage therapist I went to a year or so ago also helped me by having me develop a relaxation routine before going to sleep, trying to train my muscles to relax. Also tried to train me to "feel" again... as I had been in pain for so long she felt I had lost the ability to feel any joy in touching things. It helped some, but not enough for me to want to give up the Flexeril. When I slept "tight" a normal night's sleep was 4 or if I was lucky, 5 hours. Now, I am getting 7-9. Do any of you have this problem? I've not seen it mentioned here before. I have seen people mention waking a lot at night, but not with muscles all tight.
