My 31 year old daughter has had the EXACT same symptoms and is also worried she has MS. She has had 2 MRIs and is planning a spinal tap because they cannot find ANY evidence of MS, but she has the symptoms of MS. She got the IUD in Sep 2007 and began having strange symptoms a few months later, ranging from vision loss, dizziness, numbness and "pins and needles" feeling in her arms, legs and hands. She has seen her primary care physician, an eye doctor, an ear specialist, two neurologists, visited the emergency room with no real diagnosis. Her husband found this website and I'm ecstatic that the IUD could be the cause, but also very angry that this could happen to anyone.
