Hi Abby, That's a great question and this is my understanding. During an acute exacerbation, the blood-brain-barrier develops a leak which allows damaging cells into the CNS causing inflammation. This inflammation results in neurologic injury (sometimes with symptoms) and chronic damage to the myelin and axons. Corticosteroids help to decrease this inflammation and to close the leak in the blood-brain-barrier. The nerves should then no longer be under attack (we all hope). But depending upon how much damage might have occurred, it is hard to predict the speed and extent of recovery. You've already experienced some symptom improvement and that's great!! The body does try to repair damaged myelin on its own, recruiting young oligodendrocyte cells (yes I had to look up the spelling on that one) to repair the myelin sheath. Sometimes symptoms will resolve as this process takes place. How long that takes is unknown. I still have some residual symptoms from each attack but have regained function (ie. my left hand/fingers) through occupational therapy. Really at this point it is a "wait and see" game. I highly doubt that further damage is occurring, although it is annoying to wait. Keep in mind, however, that there are medications which can address bothersome symptoms, such as neurontin for sensory pain/buzzing, provigil or amantadine for fatigue, baclofen for spasticity, etc. I'm sorry that you're going through this right now and talk to your doctor about symptomatic treatment. Now go kiss those kids of yours and I hope you have a nice weekend.
