How will the two drugs affect me if taken together? I suffered a head injury and have post concusive syndrom. Headaches, confrusion, loss of vision in Right eye and memory loss has occoured. The accident happened in April of 2012. I have seen neurologists, opthamologists, academic opthamologists, ent doctor, and have a pain management doctor. My quality of life is less than I want and I don't want to suffer drug interactions.
