Hi there and welcome to the site -
You can find all kinds of info about this disease on the sticky poosts at the top of the forum pages that can help guide you through this. There are also amazing people here with a boatload of knowledge, compassion and understanding.
In reference to your question, in my humble opinion...it sounds like you have some good, competent and on-the-ball doctors taking care of you (you have no idea how rare that can be), and it sounds like they know what they are doing. The prednisone dosage you described sounds like a taper, which could get your platelet numbers under control possibly without having to STAY on them. I think it is NOT a good idea to "wait" it out...it can be dangerous to let this disease progress - particularly if its affecting your platelets....I strongly urge you to take your medication as prescribed, and then bring up your concerns about being on it for a long time to your regular rheumie when he gets back.
If you only end up needing a tapered dose, you will not get the more severe side effects you experienced after being on it long term. Doctors do not WANT to keep their patients on prednosone, so if they are teling you to take it, the benefit of it outweighs the side effects.
I KNOW being on it absolutely S*&#S! I am too, and have been long term in the past. But we HAVE to treat this disease as aggressively as possible sometimes...it CAN be (and I dont mean to scare you) VERY SERIOUS...Please follow your docs orders...and hang in there! Maybe the flasre will resolve much quicker this time - Let us know how you make out
