• Osteoporosis. Osteoporosis is a condition in which the bones loose so much mass that they become brittle and prone to break with slight trauma. The condition, which can occur with aging, inactivity, a low-calcium diet or use of corticosteroid medications, commonly affects the spine. When this occurs in the spine, the inner spongy bone and more solid outer portion of the vertebrae become porous. The weakened vertebrae can break – an injury called a compression fracture – and lose about one-half of their height. In most cases, compression fractures, are painful. In some cases, the resulting back pain is severe. Usually, the pain resolves within a few weeks, but for some people, it is long-lasting.
Most back pain is harmless – caused by sleeping in an awkward position, stretched muscles, overexertion, sitting down too long or falling on the ischial tuberosity (the bones of the butt that you sit on), or minor hip injuries caused by twisting a certain way during sports like volleyball. Many injuries arise simply from improper form during exercise, sports injuries, or strains.
Mononeuropathies can affect nerves in the legs, arms, or other parts of the body. Mononeuropathy means a single nerve or nerve group has been damaged, for example, by a lesion that has developed along a nerve or group of nerves. Carpal tunnel syndrome is a good example of a mononeuropathy, in this case, affecting the wrist area. With mononeuropathy symptoms may be sudden (acute) or may develop slowly (chronic). Some of the more common mononeuropathies are
Tight hip flexors can also make it harder for your glutes to activate—since they're opposing muscle groups, when one is really tight the other becomes lengthened. When a muscle is more lengthened than it should be, it takes away some of its ability to contract. When your glutes are in this compromised position, it can cause other muscles to do more work than they should, making your workouts less efficient and sometimes, increasing your risk of injury.
Why is back pain still a huge problem? Maybe this: “It is extremely difficult to alter the potentially disabling belief among the lay public that low back pain has a structural mechanical cause. An important reason for this is that this belief continues to be regularly reinforced by the conditions of care of a range of ‘hands-on’ providers, for whom idiosyncratic variations of that view are fundamental to their professional existence.”
• Osteoarthritis. The most common form of arthritis of the back, osteoarthritis is a chronic condition characterized by the breakdown of the cartilage that cushions the ends of the bones where they meet to form joints. In the spine, this breakdown occurs in the cartilage of the facet joints, where the vertebrae join. As a result, movement of the bones can cause irritation, further damage and the formation of bony outgrowths called spurs. These spurs can press on nerves, causing pain. New bone formation can also lead to narrowing of the spinal canal, known as spinal stenosis.
Grade II (moderate): A larger tear in your muscle that makes it difficult to move and causes a moderate amount of pain, especially when you move the affected muscle, swelling, and tenderness. You may have 5 percent to 50 percent loss of function and you may be limping. You can't go back to sporting activities until the tear is completely healed. These injuries can take anywhere from a couple weeks to a few months to heal, depending on how bad they are.
