Hi there. Could someone help me understand the below thread? My 3 yr old son has pans. Positive for Lyme, Mycoplasma. He had his first IVIG and it went great for a few days…then he CRASHED. All Pans symptoms got worse. We do 2nd a IVIG next week. Are people saying don’t do IVIG with Lyme or that it will cause a herx and hi just need to power through?
