First, I am sorry you are feeling so bad, especially when you have lots better things to do! It is very hard to sit on the sidelines.

The pred may take a bit longer to work. I am assuming you are still on the 40 mg? It is not unusual to have initial weakening before the improvement, so hopefully that is what you are experiencing, and you should soon improve.

If you continue to weaken, of course speak to your doctor. If you have any breathing, severe swallowing (can't manage saliva) or inability to walk without a lot of assistance, go ahead and head to ER. In the meantime--BE CAREFUL!

Hope you can get some rest before the party. I will be thinking of you--been there, done that!
