Suggest Treatment For Hand Tremors,headache And Burning Sensation In Upper Spine

These are my symptoms -- tremor in left hand when at rest, headache on left side temple, burning in upper spine radiating down the back of my arms and across shoulders(more on the left side), and now I ve added nausua and urinary incontinence to the mix. I have arthritis and was diagnosed with fibromyalgia 15 years ago for which I took effexor until I quit 3 months ago. I had a spinal infussion for pain in lumbar and cervical regions from a pain specialist for pain due to degenerative disks and arthritis. Neither of there did any good and I suffered from a spinal headache for over a month. That headache is gone, but I now have these other problems. The trembling in my left hand has been going on for several years. A doctor told me that it could be caused by long term effexor use. I have has cervical, sinus and lumbar MRIs which are negative for any problems. I am a 69 year old female. Thank you
