Vertigo With Headache. MRI Clear. Suggestions?

I have been having brief episodes of vertigo since November. these occur for about 2-3 minutes where I have room spinning dizziness followed by ringing/ocean like roaring in my left ear only, which also lasts about 2 min. I have had about 10 episodes total, with 7 happening while I've been running. The others have been while I was standing or walking around. They don't happen with specific change of position. I don't feel sick during the episodes. I don't have any hearing loss either. I have also been having very short frequent headaches that happen all over my head, for only a few seconds at a time. I had an MRI in DEc. of my whole brain that was all clear, and also showed that there was no tumor in my inner ear.
