My grandmother has paralysis in arms and legs. She went to the doctor when it first occurred. The doctor said that he could not find out what is wrong. She did come back with high blood pressure. He did a akg, MRI, and tested for diabetes. It's been 4 days and she has some feeling again in one hand and foot. The only thing different is she was sick with a cold. I don't know what it could be, please help?
