I don't understand why doctors don't seem to think the pains experienced after the infusion are not associated with the infusion. I have read many posts like yours that patients are referred here and there and probably end up going through a whole series of other doctor appointments, imaging and tests to try to figure out what's wrong. It is sad and I feel bad for anyone going through this. We are at the mercy of an overwhelmed and lousy healthcare system. My best to you!
