How to Diagnose a Bulging Disk

According to the Mayo Clinic, a “bulging disk simply extends outside the space it should normally occupy.” It may look somewhat like a hamburger that is too big for the bun. It is common to see a bulging disc on an MRI, as it is part of the normal aging process. It is also common among people who are overweight. A bulging disc does not usually cause any pain unless extra pressure is created on the spinal canal. You may also experience symptoms such as radiating leg pain, a tingling sensation, numbness or muscle weakness.

Instructions

• 1

  Receive a complete physical exam. Your doctor will need to determine the root of your pain and discomfort as there can be multiple causes for back pain. If your symptoms clearly point to a bulging disc, you may not need additional tests.

  If your doctor recommends it, you should undergo Magnetic Resonance Imaging (MRI). This form of test does not involve radiation, yet it is a very sensitive diagnostic tool. The structure of the disc is revealed in finer detail than with an x-ray. You may also be injected with a contrast dye to help further define certain parts of the spine. If you have a pacemaker or other metal device in your body, you cannot have an MRI. Your doctor may recommend a CT scan instead.

  Your doctor may recommend x-rays. A bulging disc will look like a pocket of air on an x-ray film. Since X-rays use electromagnetic radiation, you should tell your doctor if you are pregnant. Risks for an unborn baby are small, but your doctor may choose to use a different test to be on the safe side.
