How long does a closed needle last? What are the differences between long-acting and short-acting drugs?

A blocking injection is a procedure in which some drugs are injected into the diseased area to control pain. Many diseases can be treated with blocking injections, such as lumbar muscle strain and tenosynovitis. However, if you want to see good results, you have to take the injections at intervals, which is harmful to your health.

1. Blockade therapy is achieved through anti-inflammatory and analgesic treatment by injecting local anesthetics into the painful area. The interval between blockade therapy depends on the drugs used. If it is a short-acting drug, it is generally injected once every 5 days. If it is a long-acting drug, it is generally injected once every 7-10 days. If the effect is not good after 3-5 treatments, it is recommended to switch to other therapies. In addition, I would like to share with you that no matter how long the interval between injections is, it will have an impact on the body. It is recommended to do this only when necessary.

2. From the perspective of mechanism of action, blockade treatment for neck, shoulder, waist and leg pain is symptomatic treatment. There are many treatment methods used in medicine, including antipyretic, antihypertensive, diuretic, etc. Although these methods cannot fundamentally eliminate the cause of the disease, they can reduce or even eliminate symptoms and prevent complications. After one or several closed-type treatments, many patients with neck, shoulder, waist and leg pain symptoms completely disappear and never recur. Therefore, it cannot be absolutely assumed that closed treatment cannot eliminate the root cause of the disease.

3. Like other drugs, prednisolone also has side effects. Although prednisolone-type drugs are not addictive, long-term, high-dose, and repeated use can cause habituation and dependence (when giving a blocking injection in a regular hospital, the doctor will strictly control the dosage according to the patient's condition, and this rarely happens), and may produce the following side effects: centripetal obesity, body shape changes, hairy skin, beard growth in female patients, decreased body resistance to infection, slower wound healing, aggravation of gastrointestinal ulcers, and induction of hypertension, mental illness, osteoporosis, aseptic necrosis of the femoral head, etc.
