Pinched nerve, sciatica, shooting pain down the leg are all things that come to mind when dealing with a disc herniation. In between our spinal bones (vertebrae), lies a jelly-like cushion, which we call a disc. Sometimes with repeated forward bending (certain manual jobs, exercises at the gym), sneezing, coughing, can damage the disc, which can irritate a nearby nerve. This can result in pain in the local area, weakness of certain muscles, as well as pain which radiates down into the arm or leg, depending on which nerve is affected.
Most disc herniations occur in lower back, although some do occur in the neck. According to research, most disc herniations do get better by itself with time (3 months). Conservative management such as chiropractic, physiotherapy and acupuncture has been showed to help manage symptoms associated with disc herniation as well.
