I have been on only 50mgs of Topamax for migraines and love what it has done for me. The only side effect that I have experienced that I do not see posted on here is that I get these purplish/red spots on my feet and bumps under the spots that have inceasingly gotten worse over the year that I have been on the drug. If anyone else has experienced this could you please notify me. ONe other has notified me with the same type of experience, and when she weaned herself off the topamax she got rid of the symptoms. Im in the process of weaning myself off, and the symptoms are slowly going away.....please let me know if you have experienced anything similiar!!!!
