Cold pain in the cervical spine after being blown directly by the air conditioner is mostly due to the contraction and spasm of the neck muscles, tendons and ligaments caused by the low temperature, resulting in stiffness, pain and restriction of movement. General treatment, physical therapy, medication, etc. are often used as treatment methods. 1. General treatment: leave the low-temperature environment immediately and keep the neck and shoulder area warm to reduce the spasm of soft tissue pain. 2. Physiotherapy: Hot compresses, massage, baked electricity and other physiotherapy can be applied around the neck and shoulder to improve blood circulation, accelerate metabolism and relieve pain. 3. Medication: Oral diclofenac sodium extended-release tablets or ibuprofen extended-release capsules, anti-inflammatory and analgesic. If the pain symptoms are not relieved, there may be other reasons, you should go to the hospital in a timely manner, to identify the cause and give targeted treatment. The above medication should be taken under the guidance of a doctor.
