Text neck symptoms commonly include one or more of the following:
Pain in the neck, upper back, and/or shoulder. This pain may be located in one specific spot and feel intense or stabbing, or it may be a general achiness and soreness that covers a broader region, such as spanning from the bottom of the neck and into the shoulder(s).
Forward head posture and rounded shoulders. Muscles in the neck, chest, and upper back can become deconditioned and imbalanced due to prolonged forward head posture. This deconditioning can make it difficult to maintain good posture with the ears directly over the shoulders.
Reduced mobility. The neck, upper back, and shoulders may all experience some tightness and reduced mobility.
Headache. Muscles at the base of the neck could go into spasm and become painful, or pain could also be referred from the neck up into the head. Excessive amounts of time looking at screens, regardless of posture, may also increase the risk for eyestrain and headache.
