Is there a relationship between a sprained lower back and the kidneys?


Hello Dr.
Hsu, I once saw an article at a swimming school stating that people with back problems should avoid breaststroke, as it is less suitable for human anatomy.
It is better to learn butterfly or freestyle.
Does "back" here refer to the kidneys? I sometimes experience lower back pain; should I see an orthopedic specialist or a nephrologist? I look forward to your reply.
Best regards, 93.9.20.

Hello: In response to your questions.
1.
The statement that "people with back issues should avoid swimming the breaststroke" has no scientific basis, so the method you choose should be based on your comfort and injury prevention.
You may also discuss this with a swimming coach before making a decision.
2.
The kidneys are located in the lower back region.
3.
If you are prone to back strains, you should consult an orthopedic specialist.

Lower back pain can indeed be related to kidney health, but it is essential to differentiate between musculoskeletal issues and kidney-related problems. The kidneys are located in the lower back area, and pain originating from them can sometimes be mistaken for typical back pain. However, the characteristics of the pain and accompanying symptoms can provide valuable clues.

When discussing lower back pain, it is crucial to consider the nature of the pain. Kidney-related pain, often referred to as renal colic, typically presents as a deep, aching pain that may radiate to the abdomen or groin. This pain is often associated with other symptoms such as changes in urination (like blood in the urine or changes in frequency), fever, or nausea. If the pain is sharp and localized to one side of the back, it may indicate a kidney stone or infection.

On the other hand, musculoskeletal pain, which is more common, can result from various factors such as poor posture, muscle strain, or injury. Activities like swimming, especially certain strokes, can put stress on the lower back. The article you mentioned regarding swimming strokes likely refers to the biomechanics of the body during these activities. For individuals with pre-existing back issues, strokes like the breaststroke may exacerbate pain due to the position of the spine and the movements involved. In contrast, freestyle and backstroke may be more beneficial as they promote a more neutral spine position.

If you frequently experience lower back pain, it is advisable to consult with a healthcare professional. A visit to an orthopedic specialist can help assess any musculoskeletal issues, such as muscle strains, ligament injuries, or spinal problems. They can provide guidance on appropriate exercises, stretches, and modifications to your swimming technique to prevent further injury.

If there are any accompanying symptoms that suggest kidney involvement, such as changes in urination, fever, or persistent pain that does not improve with rest, it would be prudent to consult a nephrologist or a primary care physician. They can perform necessary tests, such as blood tests or imaging studies, to evaluate kidney function and rule out any underlying conditions.

In summary, while lower back pain can be related to kidney health, it is often more associated with musculoskeletal issues. Understanding the nature of your pain and any accompanying symptoms is crucial in determining the appropriate specialist to consult. If you suspect kidney involvement, do not hesitate to seek medical advice. Otherwise, an orthopedic evaluation may be the best first step to address your back pain.
