Are muscle spasms usually associated with fibromyalgia?

They certainly can be. Check out Peter, another FM sufferer, who has the same problem.

FM patients give some suggestions on how to treat them in the below URL.

I too suffer from fibro and have just recently started having musclespasms,(charlie horse type) in my legs at night. I am on valium for muscle spasms, prescribed by my pain management doc. It seems to help quite a bit. I was taking soma but it would knock me out everytime I would take it. Good luck and God bless! Survival101

Indeed they are !!!!  I too am a fibro sufferer and not only do I get them in my legs but in my back and neck as well.   Windchill

I have fibromyalgia and I get muscle spasms in my calf muscles, legs, back, nec, and stomach. I have to take a muscle relaxer to help them. Warm bathes also help.  When I seen my doctor last week I asked him if they can be associated with Gibromyalgia and he said yes it was a symptom of it.

Just today my husband said, "what is making you spasm and flail during the night"? I guess I am asleep during these episodes but now I know whay I hurt so bad in the morning. It's like someone twisted all my muscles in to knots. I only sleep the first few hours after going to bed and then I half-sleep and toss and turn the reat of the night, probably because of the spasms. I've had the calf muscle thing too that just is horrific.

Ain't it swell?
