I have recently been suffering from quite severe bouts of dizziness which come on suddenly without warning. I have had quite a few falls as a result. At other times I find it difficult to walk in a sraight line, which I know is a common symptom in MS. I have been prescribed Serc tablets. Does anyone know anything about them for the treatment of MS symtoms. My only knowledge of them is for the treatment of Menieres Disease. Any help wouldd be very much appreciated.
