School is out! Now students get a break from their backpacks or they wear them less. As soon as school restarts, wearing a backpack can be a “new” activity for the body. The pain is actually normal for the first few days.
Think of a workout – muscles are often sore after the fact. The time frame is approximately 2 to 7 days until they are back to normal and fully ready for another workout.
Wearing a backpack can also be considered a workout! After 7 to 10 days, things should clear up. If the pain does not decrease after that time, it is time to see a health professional.
