First off...sorry you still don't feel well.
I do have to say that if you are seeing some improvment in your CD..it might be from the Remicade. You might not be seeing any big results right aways..but maybe you need a larger dose. You might not be getting enough to make a big change but it still might be doing it job...just slowly.
Definetly talk with your doctor. He should have the best insight into this. I saw major improvement after my first 2 doses but after the 3rd it feels like it didn't take at all. Now my doctor is going to do a colonoscopy next week to see if it is indeed healing me and then might raise my dosage.
As far as the twitching...where exactly is the twitch. Could it be from dehydration or lack of potassium? Just a thought. Have you had any blood work done for it?
