In this case, you can use a hot water bag to apply localized hot compresses, and at the same time, pay attention to rest, and avoid prolonged sitting position, many patients can relieve the pain. If there is still no relief, it is necessary to consider kidney problems, to observe whether the patient’s urine becomes red, whether there is a lot of foam in the urine, and to measure whether the blood pressure is elevated as well as recurrent edema. If there are these conditions, it is more supportive of the possibility of kidney disease, you can perform routine urine examination to observe whether the urine protein, red blood cells and occult blood is positive, if it is positive, then it is necessary to consider that the patient is suffering from nephritis. Nephritis includes many types, so the treatment is also different, if it is chronic nephritis, need to give diuretic swelling, control blood pressure, reduce urinary protein treatment; if it is lupus nephritis, need to give hormone and immunosuppressant treatment.
