Back pain can be caused by various factors such as muscle strain, herniated discs, arthritis, or poor posture. To alleviate the pain, over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) like ibuprofen or naproxen can provide temporary relief. For more severe cases, prescription medications like muscle relaxants or opioids may be prescribed. However, it is important to consult a healthcare professional for an accurate diagnosis and appropriate treatment plan. Additionally, lifestyle changes such as regular exercise, maintaining proper posture, and using ergonomic furniture can help prevent future episodes of back pain.
