This is an example of a Valsalva-like activity (straining) inducing dizziness and headaches. Autonomic testing showed excessive increase of cerebral blood flow velocity during Phase 4 of the Valsalva maneuver, which is consistent with cerebral hyperemia. Valsalva-induced headaches are usually indomethacin-responsive.
