Pain is mostly a symptom that occurs when the nervous system is abnormally stimulated. When the condition progresses to a certain point, the pain may become the disease itself. If the pain is left untreated it can induce or lead to lesions in the corresponding organs and even make people depressed and irritable. There are quite a lot of people in life who go to the pharmacy to buy some painkillers to eat once they experience toothache, headache, etc., regardless of the cause. The patient, Ms. Wu, has been suffering from a knee joint for more than 10 years, and has been taking oral painkillers to relieve the pain episodes in order to relieve the pain. As her condition progressed, her painkillers increased from one tablet at a time to two tablets at a time. In recent times, when the pain flared up, Wu’s knee didn’t dare to move at all and she had to rely on a wheelchair to walk instead. After examination, a cyst was found in her knee joint, and after a week of hospitalization following symptomatic comprehensive treatment, Wu’s pain gradually disappeared and her wheelchair was abandoned. It is okay for pain patients to take painkillers occasionally and they do provide pain relief, but if taken for a long period of time not only does it delay the condition and prevent it from being rescued in time, but it also tends to produce some great side effects. Pain is not simply where it hurts, where to smear the medicine, or eat some painkillers. Only by clarifying the cause of the pain and comprehensive treatment can the pain be relieved. So, once you have pain, you may want to visit a pain department to find the cause, so as not to lose the best time for treatment.
