Dr./Nurses please come in...

My older sister (she'll be 31 in January) has gradually lost vision in her left eye over the last two weeks. She can't even see light now. She went to the eye doctor yesterday and they told her, her eye is healthy and they couldn't find any damage to it. Also, she has a numbness in her legs and if feels like pins and needles when she taps them. Our grandmother died of MS so we are all jumping to conclusions and my sis has been crying every night about it. She has an appointment with a neurologist on Friday, but we won't be getting the results for a least a couple of days after that. Her PCP checked her blood pressure which is good and tested her for diabetes which was negative. What else could be causing these symptoms?

TIA,
Kelly
