Among joint pains that become more noticeable with age, back pain may be the most impactful. Only after experiencing pain do we realize how vital the spine is to our body. A healthy spine is fundamental to overall health, so treating problems early when they first arise is crucial. Back pain can result from congenital causes or from poor posture and nutritional imbalances. The spinal disc is highly flexible and elastic, smoothly absorbing forces on the spine. However, as the disc degenerates, loses moisture, and loses its elasticity, it progresses into what we commonly call a herniated disc. Initially, a slightly protruding disc doesn't cause severe pain. But over time, as the amount of disc protrusion increases and it compresses and damages surrounding spinal nerves, significant pain can develop. That's why prompt and appropriate treatment is important when back pain occurs.
Back pain injections generally fall into three types: trigger point injections, prolotherapy, and nerve block injections. Trigger point injections are similar to the pain-relief injections you receive in your hip when you have a cold. When muscle pain develops, the entire muscle isn't painful — there's a specific pain trigger point where the injection is administered. Normal muscle fibers should be relaxed, but when back pain develops (from causes like herniated discs), muscle fibers become tightly contracted. Injecting solution into these contracted areas to dissolve them is called trigger point injection therapy. This helps relax the muscles and can provide significant pain relief. Prolotherapy is commonly known as ligament strengthening injection. It primarily targets soft tissues such as ligaments, tendons, and muscles. By activating the body's natural healing process, it promotes regeneration and strengthening of soft tissues damaged by sprains, while reducing inflammation. Prolotherapy is typically administered after back pain has somewhat improved, to further strengthen muscles, reduce residual pain, and prevent future problems. In other words, prolotherapy is better suited for reinforcement when muscles are weakened rather than for active disc or nerve problems. When inflammation occurs in our body, natural healing processes activate. Prolotherapy artificially triggers this healing process.
Through the tissue repair process of inflammation, growth factor proliferation, and regeneration/recovery, prolotherapy can shorten the inflammation reduction and proliferation stages, enabling faster regeneration and pain relief. By engaging cells from the regeneration stage, it promotes synthesis of key structural components, which can help further strengthen loosened ligaments and tendons. Finally, nerve block injections are used for persistent day-and-night back pain in patients with severe herniated disc symptoms. They're indicated when muscle pain is prolonged or back pain is severe enough to require rapid relief. Nerve blocks target the nerve pathway. Rather than literally 'blocking' the nerve, they 'reduce' the inflammation and swelling around nerves caused by disc herniation or spinal stenosis. Using a fluoroscopic (C-arm) imaging device for precise targeting, a needle delivers medication directly to the affected area, blocking pain signal transmission and reducing inflammation and swelling.
