I have these kinds of head aches frequently. They can start between my temples with a sharp knife like pain then become a dull pressure somewhere else. Or, visa versa. There appears to be no rhyme or reason to the locations.

I have had a string of head aches over the last 6 weeks. Then, I got hit in the head by a dropping engine part. Almost constant head aches for the past week.

Unless you have a brain bleed, which will have very serious symptoms, the location of the impact can have little to no connection to the location or type of head aches you experience.
