Bulging discs are similar to herniated discs. However, the outer casing of the cartilage usually doesn't crack with a bulging disc. A bulging disc occurs when the disc or cartilage between spinal vertebrae weaken. Consequently, the jelly-like fluid inside the disc, which is know as pulposus, becomes displaced and tends to extend into the weakened area. This puts pressure on nerves in the spinal area, causing numerous symptoms, depending on the location of the injury. Bulging discs can occur in all areas of the back, including the cervical or neck area. Bulging discs in the cervical area often cause numbness in the arms and shoulders, sending flashes of pain and numbness down the arms to the finger tips. Lumbar bulging discs, however, are far more common. These injuries usually occur between the L-4 and L-5 lumbar vertebrae, which is where the spine curves in the lower back. Individuals with bulging discs in the lumbar area may experience radiating pain in the lower back that shoots down into the hips and legs. Symptoms may be similar to sciatica, which is pain that shoots from the hip area, or highest part of the long sciatic nerve.Those with bulging discs should rest and refrain from all physical activity. It is also advisable to see a doctor to confirm the injury. Doctors will usually instruct patients with bulging discs to take ibuprofen. They may prescribe other stronger pain killers so people can better function. Those with bulging discs may also benefit from using ice at the onset of the injury, especially during the first 48 to 72 hours. Ice momentarily reduces the flow of blood and lymphatic fluid, which is the body's natural response to injuries. Ice should be used for 20 minutes about every four hours. Once the pain and inflammation have subsided, individuals may use heat for healing purposes. Heating pads or hot baths are equally effective. Heat promotes blood flow, bringing oxygen, vitamin C and other nutrients that are necessary for healing injuries. Exercise such as walking or raising both knees up while lying on a floor can help build strength in the lower back. Extra strength in this area helps support the bulging disc, and may help prevent future injuries. Surgery may be necessary if the bulging disc continues to hurt.
