Drenching sweats are often worse at night, can disturb sleep, cause severe discomfort, fatigue and affect quality of life. Patients often complain of needing to change the bedding in the middle of the night.
Differentiate from hot flushes - an intense feeling of warmth and erythema, but without sweating.
Red flags
Ask about recent chemotherapy - sweats may be a sign of neutropaenic sepsis.
