<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi: I am 45 years old women. Since last 2 year I have a lower back pain herniated disc with sciatica . I took gabapentin for 1 yearand baclofen for 5 months. My leg pain is controlled, but the soreness in back is almost always there. Doctor has recommended epidural , nerve blocker, trigger point injection with more in favour of trigger point injection. I have an appointment with chronic pain specialist coming after a long wait of a year. I want to know, what would be the best suitable for me esp what do you think about trigger point injection, its side effects if any and the after care.  <response>: Welcome to Chat Doctor Good Trigger point injection as a relatively safe and effective way to ease pain from muscle spasm. The herniated disc irritates nerves that send your muscles into spasm. The trigger point is located by your Doctor and the area is cleaned with antiseptic over the skin. Using a small needle a local anesthetic andor corticosteroid is injected. Relief can be expected from immediate effect. Side effects may include nerve damage, bleeding, infection which can be prevented by proper procedure and aseptic technique. It is indicated only to relieve pain due to muscle spasm, but as the disc herniation increases there could be more pain and spasm, but the procedure is relatively safer than Epidural.
