My doctor gave me Ultram once to get me off Norco. It did adsolutely nothing. I went back to Norco. Flexeril is another do nothing. Maybe a couple hours sleep if I am lucky. Do you have a workman comp attorney? Possibly you need a second opinion on the nerve canal narrowing. Yes, scar tissue is nothing to mess with, but a surgeon can open up the canals and free the nerves. This is what I have been told. Make sure the MRI is with contrast. Only way to really see clumping and scar tissue. I had a Myelogram to find bone spurs on the inside of the canal. This was never shown on a regular MRI prior to surgery. Good Luck and hope you get some sort of resolve for your pain.
