Kathie - So glad you are feeling better in many ways from the IVIG! I agree with 4-eyes- any thoughts to this being a side effect from the IVIG? My back can hurt from compensating from my weak trunk and whole body.. but usually after IVIG my neck and back will hurt - especially when I walk- like the jolting of the walking motions hurts my back after IVIG.. when usually that's not the case..

At my last infusion the nurse was talking about how she has a patient who gets back pain with each infusion, especially if the rate is too high..

I am a huge fan of Motrin (600mg) if there aren't any contraindications! Good luck!
