Carpal tunnel syndrome is a compression neuropathy seen worldwide, with an overall adult prevalence of about 3.8% when clinically confirmed. Symptoms often begin with finger numbness and nighttime discomfort, and risk is higher in people with factors such as obesity, diabetes, and repetitive wrist motion. On this page, you’ll explore how CTS is diagnosed, what drives risk, and which treatments—splinting, NSAIDs, steroid injections, and surgery—match different stages and outcomes.
