Hey. Thanks for writing back. I don't know what in the IUD caused the seizures. I thought maybe the hormones did. I never thought of swelling. It wasn't even something I considered. But I saw a neuro yesterday and he said he didn't see how the IUD's hormones could cause it. But what you are saying about the swelling matches up with what he said about the fluid around the brain. I really hope everyone calls and reports what their side effect are. Maybe if we all get together as a group we can get this thing taken off the market. It's to late for so many of us. But maybe we can help others. Take care. Thanks again for writing back.
