[Swimming induced vascular headache]

Area of Science:

• Neurology
• Sports Medicine

Background:

• Headaches are a common neurological symptom.
• Exercise can sometimes precipitate headaches in susceptible individuals.

Observation:

• Three patients presented with characteristic headaches after swimming.
• Headaches were throbbing, often localized to the parieto-temporal region, and accompanied by nausea.
• Symptoms recurred upon subsequent swimming and were sometimes triggered by physical exertion like squatting.

Findings:

• Neurological examinations and diagnostic tests (including angiography and CT scans) were normal in affected patients.
• Headaches resolved with rest and, significantly, ceased after swimming was discontinued.
• The cases suggest a potential link between swimming and specific headache presentations.

Implications:

• Swimming-induced headaches may be a distinct entity requiring recognition.
• Identifying and avoiding triggers, such as swimming, is crucial for managing these headaches.
• Further research is warranted to understand the pathophysiology of exercise-induced headaches related to aquatic activities.
