Headache, disorientation, nausea

Hi, I have joined here to try and hopefully get some answers. Last week I had a very bad migraine which included the 'aura' symptoms of losing vision in my left eye and numbness down my left arm. My doctor referred me to an opthamologist and I've had numerous eye tests done since, they found no problems with my eyes. However, since then I just dont feel right. I have had headaches on the left side of my head for months now, mainly above my left eye but since this migraine last week I keep feeling nausea and just dont feel quite 'with it'. The best way to describe it I suppose is a little dizzy, disoriented and just not fully 'with it'. I have another doctors appt booked for Friday but wondered if anyone had suffered the same thing and could possibly give me some advice? Thanks...
