Having pain on lower right side of head ? Brain tumor ?

I'm attaching a picture where it hurts please see it... I have marked it with red where I'm having the pain... 

It started from yesterday [13th September 2017] Now, the pain is very mild in nature and sometime I'm also pressure behind my right eye. From today I'm getting some sensation on right side above ear [picture attached]. And yes, no other "thing" happening with me like vomit sensation, nausea etc...... I'm completely fine except my hand's finger injury from bicycle LoL.... Back to the topic... do you think it's tumor or something ? 

(No, I never felt any pain on that area of my head before yesterday)

Generally, cancer/tumours don't tend to cause pain. Things like strokes are more likely to give feedback. Go to your GP, if the symptoms are worrying then they will send you for a CT scan.

But I have heard brain tumors cause pain with other symptoms... 

Hi. I appreciate your concerns but the people on this site are not medically trained and can not give you a diagnosis. RHGB has given you good advice, go to your doctor.
