Thanks for your info. The rule regarding MS is that there are no rules. MS can progress many different ways. Some patients have one attack and then nothing for many years. Other patients may have attacks back to back.
Some patients have a progressive coarse without attacks and remissions.
MRI findings change considerably and do not always correlate with the clinical findings. You can also have problems in the spinal cord that can cause similar problems. The symptoms may persist for months or may never fully resolve. You should discuss the above concerns with your neurologist. Best of luck.
