Multiple sclerosis - can symptoms come and go?

[abc]

Hi everybody,

I have been experiencing many typical MS-symptoms for years, but three different neurologists could not find a neurologic cause and suggested my difficult-to-treat Hashimoto's and my spinal muscle aches are the culprits. What I want to ask you: If you have a new brain or spinal lesion due to MS- is it possible for symptoms to come and go throughout the day (e.g. problems in the morning, no symptoms at all in the afternoon, then again in the evening) or would they stay more or less until the flare has subsided?
