Some very common postures can give you a headache!
Here's what to watch out for:
Leaning your head back to look upward toward a TV or computer monitor, or tilting the head backward to see a monitor through the near-focus part of bifocals, are common postural producers of headache.
These postures causes the occiput (the bone across the back of the head) to be stressed inferiorly. This inferiority may be more on one side or the other (unilateral) or global (bilateral).
When patients present with this in my office, it may be in combination with a superiority of the posterior part of the second cervical vertebra, an additional complication which makes the headache even worse.
I make gentle, focused, precise adjustments that correct the problems without discomfort to the patient, and I provide ergonomic counseling to help keep this from happening again.
