What advice can you give me? The left side of my head just started to hurt.

What is the pain level from 1 to 10? 1 being very little pain and 10 excruciating to the point where You have blurred vision and feel like vomiting

First thing I would do is put ice on it, and take calcium. Calcium helps with pain, a lot of people don't know this. Maybe a cup of coffee might help. A massage, hot bath or shower too. I hope you feel better soon!
