There are two types of treatment for intractable pain, medication and surgical treatment. Medication includes pain medication, such as ibuprofen for pain relief in the early stage, and a portion of pain in the later stage may require the use of sulforaphane or even morphine, and medication may have side effects. Surgical treatment currently plays a very good effect on intractable pain, for example, after lumbar spine surgery left double lower extremity pain, can be through the lumbar spine pain relief surgery method, so that the patient completely say goodbye to pain, such as diabetic peripheral neuralgia, can also be implanted in the spine electrodes, or decompression of peripheral nerve compression, can also achieve very good treatment effect. For the neuralgia of shingles, stimulation electrodes can be implanted in the spine, which can cover the painful area and make this type of patient pain free. In addition, there is a method called pain pump implantation, which can be implanted in patients with cancer pain or generalized neuralgia to perform drug pumping to control the pain.
