Optic neuritis is one of the most common initial symptoms of ms, and the numbness and tingling are also consistent.
I was diagnosed with optic neuritis just over a year ago, and I have a family history of ms. However, touch wood, I have not had any other symptoms so far, and my eyesight is now back to normal.
I'm starting to think that ms may be a lot more common than it generally believed, but that a lot of people only get one or two symptoms, and maybe improve.
For the past year, I have boosted my intake of key nutritional supplements. The most important of these is vitamin d -- there is a very high correlation between vitamin d deficiency and the incidence of ms. I also take lecithin, as well as multivitamins, fish oils, and linseed oil.
