For about 5 days now, I have been lightheaded and have had on and off headaches. Each time I have a headache, it is not very painful and is only in my forehead area. They also Do Not last very long, 10 minutes most. The symptoms get slightly wore toward the end of the day. What could cause this? Should I be concerned? What is it? Low blood pressure, brain tumor, etc. I also have had a few muscle spasms as well. In case it helps, I’m 19, male.
