Hi and welcome pOptart22! Have you read the Fibro 101 post? It's the very first post listed. Lots of great, helpful info.
I, too, take gabapentin, which helps with nerve pain issues. I also take Flexeral occasionally, which helps with stiffness, though I get quite sleepy after I take it, so it's usually late in the day.
Warm baths and using a heating pad are helpful to me for pain, as well as muscle creams. What is your pain like--stabbing, throbbing or ?? I think what we take for relief depends on what the pain is "doing," if that makes sense. Maybe gentle massage? Sometimes even wearing an extra layer of clothes can help my pain. A short rest or doing something you enjoy that's not overly active can help sometimes, but it's best to not stay in one position too long.
Hope this helps a bit. I'm sure others here will post what they use. Hope you're better soon!
Just adding that if the pain is in my head, as I often get in cooler months, sometimes steaming over simmering water helps. I think this is often sinus pain; maybe nerve pain. Just use lots of caution if you try this, of course.
