hello and welcome!
Your neuro is being incredibly dismissive of not only you, but of the years, and decades of research that goes to prove MS DOES HURT! whether its thru spastic muscles or nerve pain, IT HURTS! Your MD should NEVER dismiss your pain, even if he really thinks you are struggling and having emotional issues. he should refer you to a pain management clinic for a more thorough diagnosis and stop relying on his own opinion.
If I were you, I wouldnt walk, but I would RUN to a new neuro who listens, believes in me and is willing to go the extra mile to help me when I say im in pain.
I wish you the best of luck.
