A "fixed neck" refers to a condition where the neck is unable to move freely due to stiffness or pain. This can result from various factors, including injury, muscle strain, or medical conditions like arthritis. Individuals with a fixed neck may find it difficult to turn their head or look up and down, which can impact daily activities. Treatment for a fixed neck often involves physical therapy, medication, or in some cases, surgery. Physical therapy can help improve flexibility and strength, while medication may reduce inflammation and pain. It's important to consult a healthcare professional for proper diagnosis and treatment options.
