What is the cause of kidney pain and back pain

Some people feel swelling and pain in their kidney area, accompanied by lower back pain. This situation is actually a manifestation of kidney deficiency. Especially for gay men, if they have kidney deficiency, they may have an disharmonious sex life, lose desire for life, and become mentally depressed. Therefore, if you have the above symptoms, you must pay attention to your daily health care and participate in physical exercise when appropriate. So, what is the cause of kidney pain and lower back pain?

1. Low back pain is not specific to kidney disease, and there is no necessary connection between the two. Do not blindly confuse low back pain with kidney disease. Low back pain can be caused by many diseases. When low back pain occurs, the first thing to do is to check the location of the pain. The lumbar vertebrae are located in the middle of the waist. Bone lesions of the lumbar vertebrae, displacement of the intervertebral discs between the vertebrae, and slippage of the vertebral ligaments can all cause low back pain. There are thick muscles on both sides of the lumbar vertebrae, called psoas muscles.

Lumbar pain can be caused by contusion or sprain of the lumbar muscles, local cold, or myofibromyitis, among which the most common is lumbar muscle strain. Therefore, the location of low back pain has an important relationship with the nature of the pain. Different parts have different diseases, and not all of them are related to kidney disease.

2. The characteristics of low back pain caused by kidney disease are mostly low back discomfort, low back soreness or knife-like pain, etc. It can occur on one side or on both sides at the same time, lasts for a long time, worsens after activity or fatigue, and improves after rest. Not all patients with kidney disease experience lower back pain. When the kidneys are infected with bacteria, have renal fluid accumulation, are inflammatory and swollen, or when renal blood flow is blocked, the swelling of the kidneys will cause the renal capsule to expand, which can cause distension, tenderness, and percussion pain in the kidney area. The above-mentioned kidney diseases often cause low back pain and discomfort because the lesions cause kidney swelling, obstruction of urine flow, increased intrarenal pressure or obstruction of blood flow in the kidney.

In addition, according to statistics, half of IgA nephropathy patients experience lumbar muscle pain, the cause of which is still unknown. In addition, other kidney diseases rarely cause lower back pain. Take chronic glomerulonephritis, which is the most common kidney disease, as an example. Except for IgA nephropathy, other chronic nephritis generally do not cause lower back pain. Even if the disease progresses to chronic renal failure, there may not be lower back pain.

The above facts show that patients with kidney disease do not necessarily suffer from low back pain; and the occurrence of low back pain does not necessarily mean that one has kidney disease. If you experience low back pain, don't worry too much. First, determine the location and nature of the pain. If necessary, further examinations such as urine routine, kidney B-ultrasound, lumbar CT, etc. can be done to find out the real cause and provide targeted treatment.
