I had a massive relapse when my second child was born and was diagnosed pretty quickly. My neuro sent me for neurophisiotherapy. I went once a week for 6 months. I could not stand for more than 4 seconds without falling over (they timed me!).
I went through exercises at the appointment and then she gave me some to do at home. Make sure you do them as it wont help you if you dont do them regularly. Repetition is the key .
From what i understood is that by doing these exercises you could re-route the nerve pathways to help you with your particular problems. Different exercises to help with different probs.
Don't worry - the exercises are not too physical.
I had bad balance/extreme dizziness.
I had to do things to strengthen my core.
walking up and down a small set of steps repeatedly.
looking left and right very quickly then stopping to focus and see how long it took for dizziness to go. should improve the more you practice.
walking heel to toe down the room and reching to sides to see if i could balance myself without wobbling.
used a gym ball and did reaching exercises on it to push my balance a little more each time.
balancing on a wobble board (i fell off every time - lol!)
The idea is to challenge your weakness. Feels horrible to do this at first but it did help me.
Feel free to ask if you want to know any more.
