According to statistics, about 30% of people experience chronic diseases, among which pain makes a big difference in the quality of life of these people. There are very many types of pain with different manifestations, and chronic pain can be broadly classified into three major categories: neck, shoulder, lumbar and leg pain, neuropathic pain and cancer pain. The presence of pain should be treated, but painkillers should not be abused. If there is only an occasional toothache or stomachache and there is no related disease, some painkillers can be taken, but if they do not improve, you should go to the hospital in time. Pain caused by gastritis, gastric ulcer, etc. should take painkillers under the guidance of a doctor. In the clinic, there are patients who have stomach bleeding due to painkillers for toothache. Some patients also use physiotherapy and hot compresses to relieve pain. If they are effective, they can continue to use them, but if they do not work after several weeks of continuous use, they should change the treatment method as soon as possible. If there is shortness of breath, high blood pressure, fever and other problems, people tend to pay high attention to them, but they show a strong tolerance to pain. Pain is not something that can be tolerated and passed. We do not become more pain tolerant by tolerating pain, we only become more and more pain intolerant. If you have pain, you must treat it promptly, and never drag acute pain into slow pain, and drag a single pain into multiple pains. If the pain is acute and severe, you should go to the relevant department at the first time, such as chest pain to cardiology, abdominal pain to gastroenterology, etc. If it is a chronic pain that has been hurting for more than 1 month, you may choose to go to pain medicine to receive treatment. The pain department can treat the following types of diseases: First, neck, shoulder, waist and leg pain, including cervical spondylosis, lumbar spondylosis, herniated disc, tennis elbow, tendonitis, etc. Second, various kinds of neuralgia, such as trigeminal neuralgia, sciatica, intercostal neuralgia, residual limb pain, phantom limb pain, etc. Thirdly, cancer pain, which can be treated with antinociceptive therapy during or after cancer treatment. Fourth is pain of unknown cause . Fifth is pain caused by spasm and embolism of blood vessels and pipes . When seeking medical treatment, you must tell the doctor in detail how long the pain has been, how often it hurts, how the pain feels (such as pins and needles, cuts, tears, fire, or numbness-like pain, etc.), under what circumstances the pain will intensify or ease, and whether there are other discomforts such as dizziness and nausea when the pain is present. In short, the more accurately you describe the pain during the consultation, the better.
