While you might not have developed antibodies to the Remicade components, your increased symptoms might be a response to developing other antibodies - specifically lupus antibodies. The symptoms you described were many I developed while on Remicade. I too felt worse after my infusions. I developed lupus antibodies and ultimately, lupus itself. I think having a talk with your GI about the issue is very smart. Medications should not be making life worse.
Please do not take offense to this, but there's a huge difference between "lupus-like symptoms" and actual lupus itself. Patients tend to make the same mistake when they claim Remicade gave them MS, when in fact what results is a more general demyelinating disorder.
