Detailed Answer:
I read your question carefully and I understand your concern.

Since you do not mention it I am assuming you are not someone who suffers from primary headaches such as migraine or tension type headache (by primary it is meant that no cause can be found).

In that case any acute onset headache at your age (when it is not usual to develop primary headaches and there is higher risk for conditions like stroke) should be carefully looked into.

The first step is to check your blood pressure as sometimes that can lead to pulsating headache when high. If high and improves by therapy it can be left at that, but if normal or if headache persists even after its normalization then more looking to is necessary. By that I mean that a neurological exam is necessary for subtle neurological signs you might have missed, as well as general physical exam for issues such as ear infection, temporal arteritis (inflammation of an artery passing at the temple region), neck arthritis etc.

According to the findings head imaging and some blood tests like blood count and erythrocite sedimentation rate might eventually be necessary to check for brain lesions like stroke and blood indicators of infection and inflammation.

So you should discuss the above with your primary physician, but if he's not available these days for any reason, as I said in someone your age with no prior headache history a visit to the emergency room would also be justified.

I remain at your disposal for other question.

Brief Answer:
Neurologist

Detailed Answer:
A neurologist is certainly the most advised headache specialist.

As I said though if getting an appointment with a specialist takes time, your primary physician or the ER would be an alternative.
