why does my back hurt so much?

Your back pain is likely due to muscle strain or poor posture, especially if you sit for long periods or lift heavy objects frequently. Over time, this can cause tension in the lower back and shoulders, leading to discomfort that may feel sharp or dull. If the pain has come on suddenly, it could be a herniated disc or sciatica, which affects the nerves in your spine. Chronic pain might also indicate an underlying condition such as arthritis or osteoporosis. A visit to a doctor can help pinpoint the exact cause and suggest targeted relief, whether through exercise, medication, or physical therapy.
