“When you carry a heavy book bag or purse over one shoulder, you increase the strength of your back and shoulder muscles on one side,” Leann Poston, MD, a licensed physician and medical advisor for Invigor Medical, explains. “These muscles are held in a contracted position causing asymmetry of the back. This asymmetry pulls on the tendons, soft tissue, and vertebrae of the neck, causing pain.” Part of the problem, as Alex Tauberg, DC, a chiropractor and owner of The Pittsburgh Chiropractor, explains, is that this pain isn’t usually immediate, which may be why people don’t realize the harm they’re causing. Most people don’t feel pain just from putting a heavy bag on one of their shoulders once. It’s when it becomes a habit that this behavior causes strain, which leads to pain. “In and of itself, the strain is not harmful. Our bodies are meant to be able to adapt to different strains and loads,” Tauberg says. “The issue is when we sustain a certain strained position for a long period of time, repetitively, or at a higher load than our bodies are prepared for. When this happens, we can sustain overuse or even true strain event injuries.” Matthew Cooper, DC, an expert in physical and occupational therapy and owner of USA Sports Therapy, says the pain from these kind of neck injuries can take months to develop. And it can also manifest in different ways, according to Mona Zall, DO, a physical medicine and rehabilitation physician at the Cedars-Sinai Kerlan-Jobe Institute. A strain injury could manifest as neck pain, but it could present as neck fatigue, stiffness, or even as associated headaches, Zall says. According to Tauberg, the best way to alleviate this neck pain is prevention. He says “training your neck muscles to be prepared for the loads placed on them can prevent this type of injury.” But if you’re already experiencing pain, there may be a series of treatment methods used, Zall says.ae0fcc31ae342fd3a1346ebb1f342fcb “They include medications, modalities, and therapy,” she says. Medications used typically include acetaminophen and nonsteroidal anti-inflammatories, which can address pain in acute settings and decrease inflammation. Zall says natural remedies like massages and heat can also be used to alleviate the pain. “Once the pain has improved, therapy should begin,” she says. “Areas to focus on include posture, proper spinal biomechanics, strengthening of the muscles in the neck and upper back, flexibility and range of motion.” Of course, using these treatments and opting to never carry a heavy bag on one shoulder again won’t fix all your health problems.
