I experience very similar back and neck issues. My GP prescribed Soma (muscle relaxer) at bedtime. My Rheumatologist added Lodine (ati-inflamitory) 2x daily. The combo helps tremendously. For the time that the spasms get really intense, I'll take no more than one more Soma. Heat is always soothing. Hot baths are a slice of heaven.
Soma will help me get to sleep, but won't keep me asleep (if I'm having one of those nights). Since it's usually muscle spasm that wakes me back up, that's when I take that 2nd Soma.
Soma calms me down and, combined with the Lodine, it's the most relaxed I feel all day. The Lodine (taken 2x daily) doesn't knock me out (and I'm quite a lightweight), although it does relax me. The GP tried to prescibe Neurontin... couldn't handle it (have a 3 year old to keep up with). The Neurologist, again, tried to get me on it as well. We decided instead to give the Savella at least a month to see if it will suffice. I won't go near any synthetic opiate based pain relievers. Did that along with Elavil, Neurontin and Soma with the RSD. It was a year of living in a sleep-walk. Don't ever want to go back to that.
Reflex Sympathetic Dystrophy.
It's thought to result from damage to the nervous system, including the nerves that control the blood vessels and sweat glands.
The damaged nerves are no longer able to properly control blood flow, feeling (sensation), and temperature to the affected area. This leads to medical problems in the Blood vessels, Bones, Muscles, Nerves and Skin.
Symptoms include burning, shooting pains, muscle spasms, temp. changes (ie, cold hands), numbness and tingling in extremities, shoulders and neck.
Mine showed up after my Left Ulner Nerve got crushed when I fractured my wrist.
