If you have a small number of relapses followed by a complete recovery, you may be described as having benign MS.
Benign MS can only be diagnosed retrospectively once you have experienced little or no disability for a period of 10 to 15 years.
A diagnosis of benign MS does not guarantee that you will be free of problems, as a relapse may occasionally occur after many years in which your MS has been inactive.
Sometimes people call a period of mild symptoms right after a diagnosis "benign MS". This is often shown later to have been a period of remission.
This means that the person in fact has relapsing remitting MS - it’s just very mild to start with, or has more sensory, less mobility effects.
