Injection therapy is one of the most commonly used methods in the field of pain disciplines, but many patients may think that injection therapy is closure, and today, I want to tell you that outpatient injection therapy is never closure. What is closure therapy? Closed therapy is a mixture of local anesthetics and hormonal drugs injected into the site of pain to achieve anti-inflammatory and analgesic purposes. Long-term high-dose injections of corticosteroids can induce the production of hypertension, diabetes, peptic ulcers and osteoporosis, as well as other adverse effects such as obesity and endocrine disorders. Moreover, these complications can be long-lasting and cause long-term pain to patients and their families. Therefore, there is a reason why people often talk about “closure”. What is injection therapy? Injection therapy is mainly aimed at reducing inflammation and relieving pain, and this treatment is becoming more and more standardized. Pain doctors now do “local injection” treatment, using very low concentrations of local anesthetics and safe doses of glucocorticoids in the solution, and through a solid foundation in anatomy and various imaging (ultrasound, X-ray, etc.) visualization to guide the operation, so that the injection site is more precise, which also reduces the amount of liquid used, and therefore the related side effects are significantly reduced. In addition, depending on the patient’s condition, we also inject other drugs such as medical ozone, sodium hyaluronate, etc., which are not compatible with “closure”. Therefore, the modern treatment method is called “injection therapy”, rather than playing “closed”. The main methods of injection therapy 1, nerve root block therapy: treatment of nerve root cervical spondylosis, sciatica, herpes zoster neuralgia, peripheral nerve compression resulting in acidity, numbness, swelling and pain, etc. 2.Nerve node block: stellate ganglion block for treatment of intractable migraine, insomnia, improvement of blood supply to limbs, etc. 3.peri-ligament injection: such as rotator cuff injury and various kinds of tendonitis, inflammation of ligament injury, etc. 4.Joint cavity injection treatment: inflammation pain of various joints, such as knee joint, shoulder joint, wrist joint and other pain. 5.Injection treatment of painful points: treatment of soft tissue pain caused by muscle tension and spasm. Precautions for injection therapy 1.You should not be too full before treatment. Take a bath or wash the affected area with warm water, and notify the doctor if there is any skin breakage or infection. 2. If there is dizziness, nausea, panic or discomfort during the treatment, inform the doctor in time. 3.Sometimes the local pain can be aggravated after treatment, which is a reaction to the drug and generally reduces to disappear within 24-48 hours. 4.After treatment, numbness, fever, sweating, abnormal sensation and other reactions may occur locally and in the corresponding area. 5.After treatment, you should take a rest for about 20-30 minutes as prescribed by the doctor before leaving the hospital, and do not bathe within 48 hours after treatment. 6.After treatment, you should take rest, avoid excessive and strenuous exercise, and keep the skin at the drug injection area clean and dry for 48 hours. 7.Patients with diabetes, hypertension and coronary heart disease, please take the initiative to tell the doctor during the consultation.
