Yes, that's true that many times a person does not fully recover after an exacerbation and treatment with solumedrol. Other times, people do fully recover with no increased permanent disability. I don't know the exact statistics on how likely each scenario is, but it's definitely not unusual for someone to make a full recovery, especially early in the progression of one's disease. I'm sorry that you haven't caught much of a break in this regard and have found yourself to consistently be in the group of people who don't fully recover. But that doesn't mean everyone will have that experience.
The point I was making to the original poster still stands -- which is that she can't tell which group (fully recovering or non-fully recovering) she will be in until she gives the solumedrol a chance to work and gives her nerves a chance to heal. Although you've had bad luck (for lack of a better term) in this regard, she might have better luck. There is a good chance she will fully recover, and my point was and is just that there's no point in her being too pessimistic about her recovery until she gives it some time and sees what the solumedrol does for her. She won't know how much she'll recover until months after the iv treatment.
