Mike, I agree with Annie. COULD be the MG --- but, could be something else. Ya just never know! You need to SEE someone -- NOW!!

Also, I've heard of IVIG "suddenly" starting to "disagree" with your body. This is what happens with allergies. People are around something for YEARS -- then, one day they just develop an allergy to it. So, your body may be SCREAMING that it just doesn't like the IVIG anymore. I sure HOPE and PRAY that this isn't the case -- but, you DO need to get this checked OUT!!

Have you changed IVIG brands or anything? There might be something wrong with this brand OR this particular batch. When I had my one infusion, they were VERY particular about me letting them know about ANY unusual side-effects -- any NEW symptoms. THIS certainly qualifies!!!
