It is possible that you have a pinched nerve, this is something I live have lived with for the past 3 years. I highly reccomend finding a neurologist who specializes in the spine. There is a big difference between that type of Dr. and a General Neurologist. There are many things that they can do now a days to help. I take Neurontin and for me, it takes the pain 100% away...but it gives me brain fog. I have been taking it and dealing with that side affect for several years. some people just can not take it because the side affects are worse for them. But then you can try Lyrica and Topomax. I am just now trying Topomax over Neurontin, to see if it will work as well on my legs, but without the brain fog.
I wish you the very best.
