Hi,
I am 18 years old and female. I am a runner (6X per week 3 miles each time) and last fall I the initial symptom of flashes in my vision after runs. Then i noticed in winter i was tripping and on small imperfections in sidewalks or nothing at all. I would also skid on flat surfaces. Then is spring i would have tingling like water dripping/pricking going up my legs (usually when it was warm out). I also occasionally have sensitivity to touch of my clothing and dizziness upon standing. I have been to a neurologist and his first diagnosis was peripheral neuropathy (which my grandmother has - idiopathic). I had an MRI which ruled out MS. Blood work which ruled out vitamin deficiencies. Most recently i had an EMG which came back ... normal....does this mean that i dont have peripheral neuropathy? what else could cause all of this?

thanks so much!
