Human: My doctor says I have a herniated disc. What should I expect? Assistant: 
A herniated disc is when the jelly-like material that cushions and protects your spinal cord becomes damaged, causing pain and numbness in the affected area. Symptoms can include back or neck pain, tingling or burning sensations, weakness in the legs, and difficulty walking or sitting for long periods of time. Treatment may involve physical therapy to strengthen the muscles around the spine, anti-inflammatory medication, and rest. Surgery may be necessary if the symptoms are severe or do not improve with treatment.
