Nothing is a stupid question.
Welcome to the forum. I’m sorry you’ve had to find your way here, but now that you are, get comfortable, ask what questions you have, and if we can, someone will at least try to help.
What you’ll come to understand is that a relapse lasts as long as it pleases. No one can put a time on it. Being in hospital I assume you’re on IV steroids; people tend to expect that the steroids will ‘cure’ the relapse. Unfortunately they don’t, the point of steroids is to shorten the relapse. And they are unreliable. Sometimes the relapse will start to improve quite quickly, other times it won’t. There is no saying that when you entered the hospital your relapse was at its worst, it could just have carried on getting worse all the time.
As for how long the symptoms will last, what tends to happen is that they slowly improve over a period of weeks or even months. One day you’ll wake up and realise that you can feel and move your toes a bit better. Or that you can do something that you’d been unable to do, whether it be lift your leg up to put your socks on easier, or walk further and easier.
Massage might improve things, or you might find that you can’t stand to be touched. You’ll discover soon that everyone is different. You just need to find out what your MS will be like.
I assume that the next decision you’ll have to make will be which disease modifying drug you could/should take to ward off further relapses. You should get some help from an MS nurse or your neurologist with this decision. But once you’re out of hospital, come here and ask for help in finding out about the various drugs. You may already have been told what your options are.
Best of luck with the next few days in hospital.
