Applying ice to the neck for the first few days of pain is an effective treatment for neck stiffness, advises Healthline. Thereafter, applying heat to the neck is more beneficial. Over-the-counter pain medications, such as acetaminophen or ibuprofen, help alleviate the discomfort.
Refraining from strenuous activities and gently moving the head up and down and side to side several times a day are helpful in treating neck stiffness, according to Healthline. Maintaining good posture, changing positions from time to time, massaging the neck and using a neck pillow when sleeping all aid in alleviating neck pain and hastening a return to pain-free functioning. If neck stiffness does not resolve within a week, the neck pain resulted from trauma or other symptoms are present, sufferers should seek medical attention.
