Do kids and teens get back and neck strain?

Medically reviewed by Kristian Tarong, DC on September 17, 2026

Yes. The idea that young backs are immune does not hold up.

Back and neck aching is common in school age children and teenagers. It usually tracks with hours seated, screen position, and bag weight rather than with anything structural.

Bring the screen up

Phone to eye level rather than the head down to the phone.

Break up long sessions

A few minutes up and moving between homework blocks.

Both straps, lighter bag

Two straps spread the load. Aim around 10-15% body weight.

How long does it usually last?

Most aching in this group settles within a week or two once screen position and breaks change. Aching that persists beyond three weeks is worth having looked at.

When should you see someone?

• Aching that persists beyond three weeks
• Pain that wakes a child at night
• Numbness, tingling, or weakness in an arm or leg
• Pain after a fall or sports impact
• Aching with fever, weight loss, or a limp

How do you keep it from coming back?

• Screens up at eye level
• Both backpack straps, kept light
• Movement breaks between homework blocks
• Ask about it rather than waiting to be told

How heavy should a school bag be?

A common guideline is around 10-15% of body weight, worn on both shoulders.

Is teenage back pain serious?

Usually not, but pain that wakes a child at night, follows an injury, or comes with fever or weakness is worth having looked at.

Does phone use cause neck strain in teens?

Holding a phone below eye level keeps the neck forward for long periods, which is a common contributor.
