Chronic pain, characterized by a continuous ache that lasts for at least three to six months, can be caused by various medical conditions, including arthritis, fibromyalgia, nerve damage, diabetes, irritable bowel syndrome, low back pain, and sports injuries, among others. Alongside these discomforts, chronic pain patients may also experience fatigue, sleep disturbances, loss of appetite, anxiety, and depression, including nausea, making daily life challenging for those affected.
