First, the main business of the pain clinic: the use of nerve block therapy, knife therapy, with drugs, ultra-laser irradiation and other treatment of the following diseases: 1, headache: migraine, cervicogenic headache, myotonic headache, post-traumatic headache and. 2.Neuralgia: trigeminal neuralgia, intercostal neuralgia, sciatica, acute herpes zoster, post-herpetic neuralgia, neuropathic pain, pain after nerve injury, central pain, pain in the affected limb, stump pain, diabetic neuralgia, sympathetic nerve-related pain, complex localized pain syndrome. 3, bone and joint pain: lumbar and leg pain, cervical spondylosis, lumbar disc herniation, knee osteoarthritis, heel pain, temporomandibular joint dysfunction syndrome, degenerative osteoarthritis. 4, tissue pain: acute and chronic lumbar sprain, lumbar muscle strain, supraspinatus interspinous ligamentitis, lumbar dorsal myofasciitis, pyriformis syndrome, fibromyalgia syndrome, tenosynovitis, frozen shoulder, tennis elbow, soft tissue injury. Cancer pain: advanced cancer pain, bone metastatic pain, etc. 6, dysmenorrhea, chronic pelvic pain. 7, Painless abortion. 8, non-painful diseases: intractable hiccups (hiccups), acute facial neuritis (facial paralysis), facial muscle spasm, sudden deafness, tendon sheath cysts, vegetative nerve dysfunction. 9, anesthesia consultation: pre-operative anesthesia examination and preparation, anesthesia and post-operative analgesia program development. Second, the main business of inpatient treatment in the ward: most of the CT or C-arm X-ray imaging interventional treatment of the following diseases: 1, cervical and lumbar disc herniation: the use of CT or digital imaging C-arm intervention of cervical and lumbar disc herniation under the nucleus pulposus chemolysis therapy, radiofrequency minimally invasive neuro-interventional analgesic surgery, ozone therapy under the intervention, which can be used to treat the high cervical disc herniation caused by the cervicogenic headache, low cervical disc herniation caused by neck and shoulder upper limb pain, and the low cervical disc herniation caused by cervical and shoulder upper limb pain. It can effectively treat cervical headache caused by high-level cervical disc herniation, neck, shoulder and upper limb symptoms caused by low-level cervical disc herniation, and early control and cure patients with paraplegia tendency. For patients with lumbar disc herniation, we adopt extradiscal and intradiscal nucleus pulposus chemolysis or combined intradiscal and extradiscal chemolysis, interventional radiofrequency target treatment, interventional radiofrequency treatment of posterior spinal nerve branches, and posterior branch phenol-glycerin destruction treatment, etc. The therapeutic effect has been recognized, and its long-term effect is even superior to that of surgery. 2.Trigeminal neuralgia: The use of drugs and/or temperature-controlled radiofrequency electrocoagulation under CT intervention for trigeminal nerve semilunar ganglion destruction treatment can effectively control intractable trigeminal neuralgia. 3, advanced cancer severe pain: the general drug control of cancer pain is not ideal for the use of imaging intervention under the nerve destruction treatment can effectively control the pain. 4.Herpes zoster pain and postherpetic neuralgia: the use of persistent nerve block therapy to control pain and joint antiviral therapy can effectively treat the severe pain of herpes zoster, and can reduce the incidence of postherpetic neuralgia. Adoption of nerve destruction therapy under imaging intervention can effectively control postherpetic neuralgia. 5, vasculitis, Raynaud’s disease and other sympathetic nerve-related diseases: using CT imaging intervention under the sympathetic nerve block or destruction therapy to control or improve the pain.
