I was diagnosed with hypothyroid 35 years ago; Lupus 25 years ago, and a multitude of autoimmune disorders since then: Hashimoto’s, Sjogrens, microscopic colitis, peripheral neuropathy, raynaud’s, and other symptoms not designated as a disease yet. Recently I was referred to a neurologist who specializes in autoimmune problems due to some new symptoms. After some tests he concluded that my peripheral immune system was under attack and subscribed a five-day ivig infusion. That concluded 10 days ago and I am still suffering from headaches (not unusual) and dizziness. Yesterday I had my thyroid levels tested and my numbers were greatly changed since my last testing mid-December. My question is: could my levels of T-SHIRT, T-3 , and T-4 be affected by my ivig treatment?
