Hi,

Thank you for posting your query.

Based on your description, I would consider two possibilities:

1. Acute migraine attack- it can begin with what is called a visual aura, followed by headache and dizziness. Headaches may last upto 72 hours in migraine attacks. In rare cases, it can last upto 7 days. In cases of migraine, all tests would come normal.

2. Transient ischemic attack (TIA): In TIA, the blood supply to a part of brain is reduced for a short while. This can result in various symptoms as you described. This happens in the presence of risk factors such as high BP, sugar, cholesterol, homocysteine, etc. An MRI with MR angiogram brain would also be helpful.

Treatment should consist of migraine preventive medications such as Topiramate, divalproex, etc, and may be a low dose aspirin, till the diagnosis is sorted out.

I hope it helps. I would be pleased to answer any follow up queries.

Best wishes,
