This has been going on for a couple of days. I've had it before. No blurred vision, slurred speech, nausea, problems walking, etc. Just an area of pain in what appears to be my parietal lobe in the upper right "corner" of my skull. Anyone? Thanks.

The headache that you are describing is probably located in the parietal or parieto-occipital region.
Although, the commonest headaches are the 'tension' headaches,
certain other "extra cranial" headaches need to be considered.
There are a few such headaches which deserve mention.
- parietal headaches caused by entrapment of the posterior auricular nerve,
- occipital neuralgia, &
- Nummular headache.
Posterior auricular nerve entrapment: caused by entrapment of the posterior auricular(the first extra cranial branch of facial nerve) nerve by the sternocleidomastoid muscle.Can present after variable intervals following flexion-extension injuries of the neck.
Occipital neuralgia: These nerves, which are branches of the cervical plexus (dorsal rami of C2 and C3), pierce the nuchal fascia at the base of the skull and at this site, are therefore vulnerable to trauma from flexion/extension injuries as well as entrapment by spasm of the trapezius muscle.
Extracranial headaches generally do not respond to standard 'intracranial' headache management.They are due to nerve entrapment and therefore,need alternative approaches (local injections, surgical release etc).
Nummular headaches (coin-shaped headache): are generally of mild to moderate intensity and confined to a small circumscribed area (side-locked). The pain can be is continuous or episodic. Remissions are quite common & during remissions, the affected area may continue to be minimal sensory phenomena may persist (allodynic, paresthetic, or hyperesthetic). These headaches typically are unilateral, & commonly affect the parietal region. Some cases may be associated with underlying malignancies or diabetes mellitus. Treatment with botulinum toxin, gabapentin, or tricyclic antidepressants may be helpful.
As you seem to be describing pain localized to a very small area, Nummular headache is a strong contender.Consult your doctor for a thorough physical examination and investigations as may be necessary to arrive at a proper diagnosis.
