Migraine is a primary episodic headache. Symptoms typically last from 4 to 72 h and can be severe. The pain is often unilateral, throbbing, worsens during physical exertion, and is accompanied by symptoms such as nausea and hypersensitivity to light, sound, or smell. Auras occur in about 25% of patients, usually just before but sometimes after the headache. The diagnosis is clinical. Treatment uses triptans, dihydroergotamine, antiemetics and analgesics. Prevention is based on lifestyle modification (e.g., sleep-related habits or diet) and drug therapy (e.g., beta-blockers, amitriptyline, topiramate, divalproex).
Sports disciplines and the risk of shoulder dislocation
The shoulder joint is a mechanism that can provide movement in multiple directions, but precisely because of the versatility of the structure in excursion and mobility, the shoulder also presents an aspect of fragility, being exposed to a continuous risk of injury or dislocation.
