My girlfriend has ms and every time she has anxiety she says that 1 of her eyes has a lot of pain. is there a possibility that she lose her sight?

Friendship helps!: MS, after years of excellent research effort, still is very frustrating for accurate prognosis. Truly, the life-course of people can vary totally. Symptoms can come - and go! It's different in each - and she'll do best w/ a an MS expert doctor to guide her thru the ups and downs. Vision loss is rarely total, but is common and can be apart from eye pain.
