Chronic pain is pain that lasts more than six months and is associated with a number of diseases, such as arthritis, recurrent headaches, low back pain, etc. A survey of self-medication habits of chronic pain patients showed that about 60% of chronic pain patients are self-administering pain medication. Studies have also shown that chronic pain is a prevalent condition worldwide. Migraines can occasionally be resolved by patients taking their own painkillers. But for severe patients with frequent migraines, long-term use is not desirable because it is firstly extremely easy to develop drug dependence! Secondly, we know that the commonly used painkillers are non-steroidal anti-inflammatory drugs, which may also cause gastrointestinal damage if used for a long time. Long-term chronic intractable headache without treatment will affect physical health, such as accelerated heart rate and elevated blood pressure; secondly, chronic intractable headache will lead to psychological, emotional and mental anxiety and depression in the long run. Therefore, from these aspects, pain needs to be taken seriously and chronic intractable headache should be treated actively! Only in this way, through regular medical treatment, we can completely get rid of chronic intractable headaches without the need for oral painkillers!
