Hi there. The symptoms you describe are similar to that of M.S., but they also could be due to a pinched nerve from a disc herniation or other bony abnormality in your back and/or neck. The numbness, tingling, and bladder disturbances could be due to that. Have you had any work-up for spinal disorders? The best way to rule out these maladies is with MRI. Furthermore, as someone posted earlier, an MRI of the brain can help to diagnose or rule out M.S. If all of these tests prove to be negative, you could also request a work-up by a physiatrist who can do Electromyography (EMG) studies which measure the signal within the nerves from the brain or spinal cord to the extremities. I think if my physician told me he would never figure out what was wrong with me, I would consider finding a new physician. I hope this was helpful to you. Best of luck.
