I truly think this is an undocumented side effect. I went off Zoloft after taking it for 8 years, and a week later my so called chronic "myofascial" neck and shoulder pain and stiffness began to subside. I had never previously associated the two. Well, the other side effects of withdrawal (insomnia mostly), drove me to try Celexa. 2 days after starting, the pain and stiffness re-occurred. So I'm done with SSRI's, at least until there's a refined one without this effect. 5htp and melatonin seem to be helping a bit, as well as adding more zinc and protein into the diet.
Thanks for the replies, maybe I'm not crazy after all! Yeah right.....
