Neck problems are common and can result from poor posture, prolonged screen use, muscle strain, stress, injury, or degenerative conditions such as arthritis. Common symptoms include neck pain and stiffness, limited range of motion, headaches, shoulder pain, and sometimes numbness or tingling in the arms. Treatment depends on the cause and may include rest, posture correction, physical therapy, pain-relief medications, and complementary therapies such as acupuncture, which can help reduce pain, relax muscles, and improve mobility.
