Relapsing Remitting Multiple Sclerosis (MS) is the most common type of Multiple Sclerosis (MS). where symptoms occur, in a relapse, and there is then recovery or remission of those symptoms. The time frame of the relapses is much variable with some people having relapses every four to six months, whereas other will have a relapse every two to three years. The relapse can last a few days to a few months, and the time scale for recovery is similar.
More than two relapses in a year would be considered as an aggressive MS and warrants consideration for a disease modifying course of medication. The individual relapses can be treated with high dose steroids either as injections or orally, under the advise of the neurologist.
