I am pretty healthy person, I dont smoke, no drugs, occasional alcohol and in shape.
I had an episode about 2 months ago where I was sneezing and as a result had a sharp pain in my head. A few hours later the right side of my face and arm started to get numb. I went to the emergency room, took a ct scan and nothing showed up. Symptoms subsided but I constantly had a mild headache and mild numbness on my right side. Had a mri/mra and nothing showed up. Nothing on my blood tests either. Everything else is pretty normal except my symptoms. My right side also feels weaker than normal and I get fatigued in the afternoons.

My doctor said it was not a stroke or tia. Now I am really confused.

What could it be? I was hoping that it was just a fluke but I am very concerned.
I am scheduled to do some emg tests. Maybe I have muscular dystrophy?

Does anyone have any idea what it could be?
