I too am sorry that you're symptoms have increased, but you will be in for the MRI in just a few weeks and hopefully then you can get some answers. Are you working with your neuro regarding the headaches? You might want to get a referall to a headache specialist (usually a neurologist who specializes in headaches). As a fellow "headacher" I feel your pain. It is draining to have the pain everyday and the pain cycle needs to be broken.
I'm not a Dr (obviously), but I have been through many meds, nortryptaline has been great at night, made me feel very tired in the beginning, but it helps with the nerve pain and lets me sleep better. The other med I'm taking is indocin/indomethecin, this is a non-steroidal anti-inflamatory and helps somewhat, more when I first started taking it. This medication is very hard on the body (especially stomach) and I'm taking the maximum dose, so we will be changing meds soon. We're going to try Topomax first to see if that helps, but if not then gabapentin/neurontin. I have heard of Lyrca and I know there are a couple people taking it or who have taken it. Soundy is the one that comes to mind and I think Scarlett as well?
My advice for the neck pain is ice, and use it multiple times a day, especially at night before bed. Also look for some of Capt Deb's threads on headaches as she is the resident headache expert.
Take care and keep us posted regarding your MRI and symptoms.
