Why do the shoulder, neck, and back hurt after carrying a heavy backpack?

Hello,

Welcome to icliniq.com.

I went through your query and understood your concern.

I suggest you adjust the straps to keep the pack snug against your back. Position your pack between your shoulders and hips. Your backpack should hang just below the shoulders with the bottom in your low back curve. Never let it hang more than four inches below your waist. Look for features like wide, padded shoulder straps, and air-filled cushions. Wear shoulder straps over both shoulders. Slinging the straps over one shoulder increases strain and can cause you to lean to one side. Use waist belts to shift work to your trunk and hip. I also suggest you use a wheeled backpack for the heavy loads if carrying for long distances, and arrange items so that they do not shift.

I hope this has helped you.

Thanks and regards.
