Headache appeared 1-2 weeks after banging head

[Auburngal]

2-3 weeks ago I banged my head on the shower tap and it was sore rest of day and the next.

Then a week ago, the headache came back roughly in the same area where I banged it. Its above left eye. Only subsides a bit with painkillers but I don't want to take painkillers. I feel a bit nauseous and 'not with it'.

I am not the headachey type of person.

Should I see a GP about this?

It would seem a wise move if it's now not going away and in the same location.
