Kidney Pain: Causes and When to Seek Help

Kidney pain

I sometimes feel pain in my kidneys, but it's not very intense.
However, it tends to hurt more when I exercise, especially during my menstrual period.
What could be the reason for this?

What you may be referring to is "lower back" pain.
In addition to the kidneys, the lower back also contains muscles, fascia, and other structures.
Further examination is necessary to determine the cause, so please consult a nephrologist for evaluation.

Understanding kidney pain can be quite complex, as it can stem from various causes, some of which may be related to the kidneys themselves, while others may be due to surrounding structures or even muscular issues. When you experience discomfort in the kidney area, especially during physical activity or around your menstrual cycle, it is essential to consider several factors.

Firstly, the kidneys are located in the lower back, and pain in this region can often be mistaken for kidney pain. In many cases, the discomfort can be attributed to muscle strain or issues with the spine, such as a herniated disc or muscle spasms. If you notice that the pain intensifies during exercise, it could be due to muscle fatigue or strain, particularly if you are engaging in activities that involve bending or twisting motions.

Additionally, hormonal changes during your menstrual cycle can lead to increased sensitivity and discomfort in the pelvic and lower back regions. Prostaglandins, which are chemicals released during menstruation, can cause muscle contractions and inflammation, potentially leading to referred pain in the kidney area. This could explain why you feel more discomfort during your period.

Another possibility is that you may have underlying kidney issues, such as kidney stones or a urinary tract infection (UTI). Kidney stones can cause sharp pain that may radiate to the lower back and can be exacerbated by physical activity. UTIs can also lead to discomfort in the kidney area, especially if the infection is severe or has spread to the kidneys (pyelonephritis). Symptoms of a UTI may include frequent urination, burning sensation during urination, and sometimes fever.

Given your symptoms, it is crucial to monitor the pain and any accompanying signs. If the discomfort persists, worsens, or is accompanied by other symptoms such as changes in urination, fever, or blood in the urine, it is advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, including a physical examination, urine tests, and possibly imaging studies, to determine the underlying cause of your pain.

In summary, while occasional mild discomfort in the kidney area may not be a cause for alarm, it is essential to pay attention to the context in which the pain occurs. If it is linked to physical activity or your menstrual cycle, it may be related to muscle strain or hormonal changes. However, if the pain is persistent or accompanied by other concerning symptoms, seeking medical help is crucial for proper diagnosis and treatment. Early intervention can help prevent potential complications and ensure that any underlying issues are addressed effectively.
