I have leg pain too. Starts in my hip shoots down to my foot on some occasions usually with much use. At this time my neuro thinks its arthritis and is sending me to get an X-ray.
I have also had shoulder/arm pain. That pain radiated from the shoulder to my fingertips in some cases the elbow to the fingertips. (Both arms different times) The elbow pain was believed to be tennis elbow. I did have a surgery on my right shoulderfor calcific tendonitis. Was scheduled to have the left one done when I developed the optic neruitis.
Some months later I had the numbness in my left hand and was sent for an MRI of my spine and they found a lession there. My Orthopedic doctor won't touch my shoulder now that I have been DX with the MS.. To be honest, The shoulder hasn't bothered me since the year of my DX. Makes you wonder...
