Sorry you're still having such a bad time. I've only had success with oral steroids once, and it was a minor flare. It doesn't sound like you are going to improve quickly without the IVSM. I did a 6 moth "push" with IVSM a couple of years ago, and was symptomless for about 3 months after, and only very minor sx for another 4-5 months. That was three days back to back IV's then once a month for six months. It was a pain, but being sx-free was amazing, if only for a little while!
