Myofascial Pain Syndrome Support Group
Myofascial Pain Syndrome (or MPS) is a term used to describe one of the conditions characterized by chronic pain. It is associated with and caused by "trigger points" (TrPs), sensitive and painful areas between the muscle and fascia. The symptoms can range from referred pain through myofascial trigger points to specific pains in other areas of the body. It may be related...

However, it really depends on what physical symptoms you are looking to find relief for.
Best wishes.

Sertraline to help muscle pains? Well, I've been taking sertraline since october 2010 for the stress-induced depression and throughout that time it really hasn't done anything to my muscle pains and stiffness.
It's definately helped reconnect my shattered emotions and darker than dark moods, but I've paid a high price for this assistance. I started at 50mg, increasing in 50mg increments to maximum dose of 200mg. The side effects seemed to get worse with each increase, and, for me, are mainly psychological - the first time I got so out of it I couldn't function enough to cross the road, plus I remember not being able to add up coins in my purse. By far the worst side effects have been 'irrational thoughts' that always seemed to sneak in towards the end of the induction phase.
So that's my experience of sertraline. It's helped my mind, not my muscles.
I did a Google search and found that SSRIs are prescribed for fibro if sleep issues and day time fatigue are the problem. The below exert is from the NY Times.
Selective Serotonin-Reuptake Inhibitors. Selective serotonin-reuptake inhibitors (SSRIs) increase serotonin levels in the brain, which may have specific benefits for fibromyalgia patients. Commonly prescribed SSRIs include fluoxetine (Prozac), sertraline (Zoloft), paroxetine (Paxil), and fluvoxamine (Luvox). Studies suggest they may improve sleep, fatigue, and well-being in many patients. Studies are mixed on whether they improve pain. SSRIs should be taken in the morning, since they may cause insomnia. Common side effects are agitation, nausea, and sexual dysfunction, including a delay or loss of orgasm and low sex drive.

I haven't taken an SSRI and can't give you my experience. My gut reaction is that if nothing else has worked, what do you have to lose by trying it? Good luck, Bullring. I'm glad to see you around.
