Discomfort in the left side of my head above Temple, what could it be?

So I’ve been feeling this for the past couple months. I have a discomfort in my head, I’ve had headaches but those have gone. I’ve also had slight dizziness and I did experience burry vision but not recently, I feel kind of weak all the time but nothing serious. I’m scared it could be a brain tumor but I guess I could just be getting myself worked up. 

Try Ultimate PAIN Fighter it has gotten rid of my headaches faster than anything else! 

Suffered for years with migraines and now whenever I feel a headache coming on I put on UPF and it relieves it usually in less that 5 minutes!!! Nothing has ever worked that fast for me! You just gotta try it!!!
