Backache refers to pain or discomfort in the back, which can occur in various areas, including the lower back, middle back, or upper back. It is a common condition that can result from factors such as poor posture, muscle strain, or injury. Backaches can be acute, lasting a few days, or chronic, persisting for weeks or longer. Many people experience backache at some point in their lives, and it can affect daily activities. Treatment options include rest, physical therapy, and over-the-counter pain relief medications. Maintaining a healthy lifestyle, including regular exercise and proper ergonomics, can help prevent backache.
