Sudden severe headache and sweating after spinal cord injury: first sit the person upright, loosen tight clothing, and call 120
In people with spinal cord injuries, the body’s warning signals get disrupted. Even if the bladder is full or clothing is too tight with no obvious discomfort felt, blood pressure can spike dramatically. The main warning signs are sudden severe headache and excessive sweating. In such cases, the first steps are to help the person sit upright, loosen any tight clothing, check if the bladder is full, and call emergency services right away.

No cost at all. Just three simple actions that take only a few dozen seconds to perform.
This type of episode is known as autonomic dysreflexia. A systematic review examined four major medical databases — Medline, CINAHL, EMBASE, and PsycINFO — and included 31 studies, 6 of which were randomized controlled trials. The review confirms that the recommended non-drug treatment consists of three steps: positioning the patient upright, loosening tight clothing, and removing any triggering factors. These steps are supported by clinical consensus and physiological evidence, and are classified as Level 5 evidence. Antihypertensive medications are only used when blood pressure remains elevated; prazosin has Level 1 evidence, while nifedipine and prostaglandin E2 have Level 2 evidence. Preventive measures mainly target common triggers such as urinary retention and surgical procedures, though most such strategies are backed by Level 4 or 5 evidence.

Open source linkThis grade is assigned because there are no randomized controlled trials directly supporting those three on-site actions — only clinical consensus and physiological reasoning. The review itself notes that most of these interventions are supported by non-controlled studies. Medication use is strictly a medical professional’s responsibility; laypeople should never administer antihypertensive drugs at home. Lying down can further raise blood pressure, so sitting upright is essential. Family members and caregivers must also learn these three steps. This condition must never be mistaken for ordinary headaches.
