My 52 year old daughter has turrets, and occipital neuragia, She is taking many (15) different medications, she is out of percogesic, I have come across her prescription from several weeks ago of Dilantin,which had been prescrbed for her, I m hoping it will help her pain, she now is only able to see from her left, and not very clearly,.It is Heartbreaking to us as parents. She has a Docters appointment on Wednesday, the 16th. Have you a suggestion? Thank you so very much, for your time, and consideration, her Mother, Carol.
