Feeling symptoms again

We'd appreciate your prayers. Rhonda had a horrible night. She feels like she's feeling all of the same symptoms again with some other ones (nauseau). We called the neurologist at 6am this morning. He said it is unlikely it is a relapse, but said sometimes at three weeks they need to give a booster treatment. He will be ordering another treatment of immunoglobulin (outpatient) today. We're just waiting and enduring.
