Migraine is different from ordinary headache, the damage caused to patients is more serious than ordinary headache disease, the use of injection treatment is more effective, so what are the precautions for injection treatment of migraine? How often should the injection be given? How many injections is a course of treatment? How long does a course of treatment take? How often you have to come in for an injection is determined by the patient’s injection site. Conventional paracervical injections (injections on the side of the neck) are given once a week to once every two weeks, and a course of three to five injections is required, which is about a month to a month and a half. Stellate ganglion block treatment (injections in the front of the neck) requires injections once a day or every other day, with ten injections as a course of treatment. It is important to remind patients that nerve block therapy for migraine is given on a regular basis, not on demand, and that the injections must be given on a regular basis, not just at the onset of pain. How many courses of treatment do patients usually need to do to achieve a more desirable treatment effect? How long it takes to achieve a more desirable treatment effect is determined by the patient’s condition and personal constitution. Some patients with short headaches have very good results after one course of treatment, and with the patient’s adherence to rehabilitation exercises, the treatment effect can be maintained without the need for a second course of treatment. There are some patients who have had headaches for a long time and may still have attacks during treatment, but the frequency and pain level of the headaches will decrease. If this is the case, at the end of a course of treatment, the doctor will continue to observe the patient for one to three months before starting the next course of treatment. Generally, most patients will produce better results after two to three courses of treatment. If the headache does not improve after two to three treatments, the doctor will choose other treatments depending on the patient’s condition. Will the patient feel any pain during the nerve block injection treatment? Will there be any other discomfort? Nerve block requires a needle to puncture the skin. Patients will feel a slight stinging pain during the puncture, which most people can tolerate. However, if the patient is weak, nervous or sleep deprived, the injection may cause “dizziness” – feeling dizzy, nausea, etc. If this happens, there is no need to worry too much, the patient will be relieved after a while. How long does it take to perform each treatment? Does the patient need to be hospitalized? The operation of this nerve block treatment is very fast and can be completed in about five minutes if only one area is injected. After the injection the patient needs to rest in the hospital observation room for about 10 to 20 minutes for the purpose of observing if any adverse reactions appear and if there are none the patient can go. The entire treatment can be performed in an outpatient clinic and the patient does not need to be hospitalized and can go home the same day. Is a patient usually treated with only one of the above mentioned nerve block methods or multiple methods at the same time? Will multiple methods aggravate the side effects of the medication? The specialist will choose based on the severity of the headache and the characteristics of the pain. If the patient’s pain is short-lived and the pain is in a single location (only in one place and does not move around), one method is sufficient; if the pain is long-lasting, two or three nerve block methods will be chosen to treat the patient together, and the effects of multiple treatments will be mutually reinforcing. The doctor will consider the dosage and side effects of the medication when taking multiple methods together, so the patient does not need to worry too much. Do I need other complementary treatments after having nerve block injections? There are many causes of headaches, and doctors will use multiple methods of treatment depending on the patient’s specific condition. For example, if a patient has persistent insomnia, if only nerve block treatment is given, his headache will still come back easily and the doctor will have to use sleep medication or other complementary treatments. Will it not work if I use the same medication for a long time? Long-term use of the same medication will definitely lead to drug resistance. Many headache patients have the experience that half a tablet of a painkiller works at the beginning, but several tablets or even dozens of tablets do not work. This is one of the reasons why we emphasize multifactorial treatment, instead of relying solely on one type of drug, a “multi-pronged” approach to treating the disease can reduce the resistance to one type of drug.
