What is a tweak in the back?

A tweak in the back typically refers to a minor injury or strain in the muscles or ligaments of the back, often resulting from sudden movement, poor posture, or overexertion. Symptoms may include discomfort, stiffness, or limited mobility, but it usually resolves with rest, gentle stretching, and over-the-counter pain relief. While most tweaks are not serious, persistent pain should be evaluated by a healthcare professional to rule out more significant issues.
