She caught norovirus on a cruise.
Hours bent forward on the toilet.
Violent vomiting with diarrhea.
A crushing pressure behind her eyes.
The virus passed. The pressure did not.
Even on calm days she lived at a seven out of ten.
Headache all day.
Blurry vision.
Tunnel vision.
Then bathroom trips spiked it to a ten.
Two years of normal scans.
Normal eye exams.
Normal GI testing.
Several rounds of gut treatments.
Nothing explained why constipation and stress made the pressure surge.
On exam the driver was below the belt.
That illness had locked her pelvic floor in guard.
The floor would not relax when it needed to.
Resting abdominal pressure stayed high.
Veins from the brain and eyes drain into low‑pressure pathways through the neck and chest.
When abdominal pressure runs high all day, that drainage struggles.
You feel a heavy, inside‑the‑skull pressure.
Vision narrows at the edges.
Then you strain on the toilet and the spike is instant.
We changed the loop.
Pelvic physio downtrained the floor and retrained defecation without pushing.
Breathing that couples diaphragm and pelvic floor.
Stool mechanics that do not require force.
I treated the neck for the fallout from weeks of guarding and rebuilt cervical and scapular control.
Her baseline fell.
Bathroom trips stopped being a trigger.
The constant seven faded.
Her vision steadied.
Focusing got easier.
If your head or eye pressure rides with constipation or stress, widen the search.
Normal scans can miss a mechanical loop.
Screen the pelvic floor. Help the floor relax. Restore flow.
Red flags still matter. Sudden worst headache, progressive visual loss, double vision, weakness, or thunderclap pain need urgent medical care.
