Aponeurosis of scalp: You probably pulled and strained the scalp and the aponeurosis which can give you a headache like the one you described. Apply ice and use over the counter remedies if you tolerate them. Leave it alone for a couple of weeks and it should heal. If there is swelling, you could have a hematoma (extracranial) and should be seen to possibly relieve the pressure.
