Should I apply ice or heat to an injury?
Ice should be used in the acute stage of an injury (within the first 24-48 hours), or whenever there is swelling. Ice helps to reduce inflammation by decreasing blood flow to the area in which cold is applied. Heat increases blood flow and may promote pain relief after swelling subsides. Heat may also be used to warm up muscles prior to exercise or physical therapy.
What is physical therapy?
Physical therapy is the treatment of musculoskeletal and neurological injuries to promote a return to function and independent living. Physical therapy incorporates both exercise and functional training. Exercise restores motion and strength while functional training facilitates a return to daily activities, work, or sport.
What is a cortisone/corticosteroid injection?
Cortisone is a steroid that is produced naturally in the body. Synthetically-produced cortisone can also be injected into soft tissues and joints to help decrease inflammation. While cortisone is not a pain reliever, pain may diminish as a result of reduced inflammation. In orthopaedics, cortisone injections are commonly used as a treatment for chronic conditions such as bursitis, tendinitis, and arthritis.
What is an epidural?
An epidural is a potent steroid injection that helps decrease the inflammation of compressed spinal nerves to relieve pain in the back, neck, arms or legs. Cortisone is injected directly into the spinal canal for pain relief from conditions such as herniated disks, spinal stenosis, or radiculopathy. Some patients may need only one injection, but it usually takes two or three injections, given two weeks apart, to provide significant pain relief.
What are NSAIDs and how do they work?
Non-steroidal anti-inflammatory drugs (NSAIDs) are non-prescription, over-the-counter pain relievers such as aspirin, ibuprofen, and naproxen sodium. They are popular treatments for muscular aches and pains, as well as arthritis.
NSAIDs not only relieve pain, but also help to decrease inflammation, prevent blood clots, and reduce fevers. They work by blocking the actions of the cyclooxygenase (COX) enzyme. There are two forms of the COX enzyme. COX-2 is produced when joints are injured or inflamed, which NSAIDS counteract. COX-1 protects the stomach lining from acids and digestive juices and helps the kidneys function properly. This is why side effects of NSAIDs may include nausea, upset stomach, ulcers, or improper kidney function.
What is the difference between x-rays, MRI, and CT scan?
X-rays are a type of radiation, and when they pass through the body, dense objects such as bone block the radiation and appear white on the x-ray film, while less dense tissues appear gray and are difficult to see. X-rays are typically used to diagnose and assess bone degeneration or disease, fractures and dislocations, infections, or tumors.
Organs and tissues within the body contain magnetic properties. MRI, or magnetic resonance imaging, combines a powerful magnet with radio waves (instead of x-rays) and a computer to manipulate these magnetic elements and create highly detailed images of structures in the body. Images are viewed as cross sections or "slices" of the body part being scanned. There is no radiation involved as with x-rays. MRI scans are frequently used to diagnose bone and joint problems.
A computed tomography (CT) scan (also known as CAT scan) is similar to an MRI in the detail and quality of image it produces, yet the CT scan is actually a sophisticated, powerful x-ray that takes 360-degree pictures of internal organs, the spine, and vertebrae. By combining x-rays and a computer, a CT scan, like an MRI, produces cross-sectional views of the body part being scanned. In many cases, a contrast dye is injected into the blood to make the structures more visible. CT scans show the bones of the spine much better than MRI, so they are more useful in diagnosing conditions affecting the vertebrae and other bones of the spine.
