A spinal herniated disc occurs when the inner soft center of the spine pushes out of the external protective spinal casing. This may be due to age-related degeneration or back injuries. Whatever the reason for the herniated disc, sufferers undergo a lot of pain and discomfort. Any movement that aggravates the herniated disc should be avoided without question. If the sufferer is dedicated to practicing yoga daily, then there are a few yoga poses that should not be practiced in their full form. The yoga poses mentioned below should be performed with their modifications and variations so that the herniated disc is not exacerbated in anyway.
