Hi - My sister is 72 years old. In good health. Recently experiencing headaches, blurred vision and nausea. Went for an MRI and her doctor thought the potential of MS. They referred her to a neurologist. In the meantime she is complaining of fatigue, sore throat, painful gums and food tastes bad. She is also experiencing pain in all areas except for her legs. She says she just does not feel right.
