Pain caused from excessive loads has gained the term “backpack syndrome.” Backpack syndrome causes headaches, neck and back pain, and fatigue. There have been studies examining the effects of carrying backpacks on one shoulder versus both shoulders. Carrying a bag on one shoulder causes significant asymmetries.
The longer someone carries extra weight, the worse the condition and body posture get. Over time, the person can experience pain, flexibility problems, stiffness, and reduced range of motion.

Slinging a backpack over one shoulder can cause a person to lean to one side to compensate for the uneven weight. This can curve the spine. Over time, this can cause lower and upper back pain, strained shoulders and neck, and even functional scoliosis (curvature of the spine).

Some studies recommend only carrying a load of 30% of your bodyweight. Others, however, have reported participants experience discomfort carrying 20% of their bodyweight when exercising for more than an hour. To avoid this when starting out, carry a backpack that's as light as 5-10% bodyweight.
It can cause poor posture, compressed discs in the spine, and even curvature of the spine. Straps digging into the muscles of the shoulder were also found not just to irritate the area, but to cause potential damage to the nerves of the hands and arms. These issues aren't just small problems.
Walking outdoors with a weighted backpack builds strength, endurance and clears out the cobwebs. “Rucking” is a form of military training. People are discovering its mental-health benefits, too.
Walking, hiking or running with a weighted backpack is known as rucking. It's a tough workout that can help you build endurance while also gaining muscle, said Michael O'Dowd, tactical expert for the fitness brand Ten Thousand with nine years of experience as a SEAL.

This type of paralysis can occur when a backpack overloads our shoulder girdle, causing the shoulder blades to sag down dragging the collarbones with them. The collarbones will then compress the delicate long thoracic nerve against our rib cage and it is this nerve compression which causes the paralysis.
Scoliosis is not a condition caused by carrying a heavy load (not even a very heavy one). Scoliosis is also not caused by childhood sports injuries, heavy backpacks full of books or hiking gear. Heavy loads may cause back, neck and shoulder pain, but scoliosis develops in different ways.
