Hit the right side of my head in the temple area two days ago. i had pain/pressu in that area for a few hours or so. no headache/unconscious/dizziness.there is still very faint pressure, get worse if i press on that area like a bruise.shall i worry?

Not likely. Local bruises from a knock on side of head would not be uncommon. Slight pain normal. Unless you are experiencing more severe symptoms, you should monitor your head for changes.

You describe superficial head trauma with a localized bruise ("goose egg"). This was NOT a concussion, and will not be a traumatic brain injury. If you are prone to worry, have your primary care provider evaluate.
