I am a 21 year old female and have been on Topamax since October of 2006. I am up to taking 250mgs a day having a constant headache and getting a migraine about every week. I have had such a range of side effects and symptoms that I can't tell the difference nor know where to begin. The most recent is muscle spasms in my eye lid and leg that won't go away. I have spasms infrequently all over, but these have been pretty constant. I also tire very easily though I always get 8 hours of sleep a night. Though those are not always 8 full hours of sleep, because I do have boughts of insomnia. I have also dealt with the intestinal problems to the point of thinking that I had appendicitis. I have had multiple trips to the hospital for abdominal pain and severe migraines. I have had the vision problems - blurred, dizziness, vertigo, and the weird one were my eyes jerk back and forth. I rarely have all at once and they have come and gone throughout the 2 years, but they have come back I think the most mysterious one of all are the lypomahs - these little painful nodules under the skin that just appeared. They are mostly on my abdomen, but have found them on my chest as well. Any one else heard of this?
