I am aware you can have EBV and not know it.

I had urinary retention starting at the age of four w/repeated UTIs to the point of using antibiotics monthly. MS or another cause? No doctor (Urologist) knew why I had retention problems and repeated cathing never made a difference.

There were other signs of MS in early childhood.

I had 2 1/2 feet of intestines removed when I was 2 years old. There were no nerves in that section. This is called Hurshbrungs(sp) disease.
I have always found it rather ironic that I have a neurological disease and yet had a disease where there were no nerves where there was supposed to be.

I don't discount EBV or any virus as a trigger for MS. I am just skeptical EBV was the trigger for my MS.
