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 showed a hyperintense spot on my brain but the neuro said the location ruled out MS. Blood work which ruled out vitamin deficiencies. Most recently i had an EMG which came back normal. Could this still be MS? i feel like my symptoms most closely match MS (our air conditioning broke and now with the heat i am having a lot of tingles and sensations in my legs). or is there something like MS which could be causing this?

thanks so much!
