What should I do if I have a stiff neck?
I bought a new pillow yesterday, and it's too high, causing me to sprain my neck. What should I do for a stiff neck?

Neck sprain is a common soft tissue injury of the neck, usually caused by improper sleeping posture or exposure of the neck to cold. The following measures are recommended:
1. Rest and protection: After a neck sprain, allow the neck muscles to rest sufficiently. Avoid strenuous activities and reduce strain on the neck. Use a neck brace for protection to prevent further injury.
2. Gentle exercise: Perform mild stretching and rotational movements of the neck, but avoid excessive force that may worsen symptoms.
3. Heat application: Apply heat to the affected area to relieve pain. Each session should last approximately 15-20 minutes, which can promote blood circulation and alleviate muscle tension.
4. Cold application: Apply ice to help reduce pain and inflammation.
5. Physical therapy: Treatments such as electrical stimulation or ultrasound may help relieve muscle tension and pain and accelerate recovery.
If symptoms persist or are accompanied by severe headache or arm numbness, seek medical attention promptly to rule out possible complications such as cervical spondylosis. Maintain good sleeping posture and keep the neck warm. If symptoms persist or worsen, it is recommended to seek timely medical care.
