You may have: neuritis or neuralgia from local nerve irritation in the temporal region of your scalp. Or you may have infection of the cranial or oculomotor nerve by a virus such as herpes or zoster (shingles). Please see a healthcare provider ASAP. Thanks for trusting in HealthTap.

There are certain: types of headaches that actually cause tenderness or pain to the touch including migraine or some type of neuropathy/nerve impairment. This feature isn't really alarmingly in and of itself. Do what you usually do for a headache--rest, dark room, OTC pain killers--but if this feature persists, see your doctor for evaluation. Stay well:)

See dentist: You may have a jaw problem from grinding or clenching your teeth especially when sleeping. Suggest you get your jaws checked. If nothing there, then perhaps a MRI may be in order if the problem has been present for more than a few weeks or is getting worse.
