Is it lower back pain or kidney pain?


Hello Dr.
Lai: Recently, I have been experiencing a lot of pain near my lower back.
My friends say it might be related to my kidneys.
Due to work commitments, I haven't been drinking much water and often hold my urine.
Lately, the pain near my lower back, which is close to the kidneys, has been quite severe, so I would like to ask you what I should do.
Thank you for your help!

Hello: Most cases of lower back pain are not related to kidney issues.
If there is no swelling, it is advisable to drink more water.
Kidney pain may originate from back muscle strain or nerve pain, and it could also be due to kidney stones.
If there is an infection in the urinary tract that ascends to the kidneys, kidney pain may occur, accompanied by fever and other discomforting symptoms.
Kidney problems are typically indicated by changes in urine color or foamy urine.
It is recommended that you first consult a family medicine physician for an evaluation before making further assessments.

When it comes to distinguishing between back pain and kidney pain, it is essential to understand the underlying causes and symptoms associated with each. Your description of pain in the lower back area, particularly near the kidneys, raises several important considerations.
Firstly, kidney pain typically presents as a deep, dull ache that is often felt in the flank area, which is located on either side of the spine, just below the rib cage. This pain can sometimes radiate to the lower abdomen or groin. In contrast, back pain can be more localized and may be associated with muscle strain, poor posture, or spinal issues.
Given your situation, where you have been holding in urine and not drinking enough water, there are a few potential issues to consider. Chronic dehydration can lead to kidney problems, including kidney stones or urinary tract infections (UTIs), which can cause significant discomfort. Holding in urine can also lead to bladder distension and potentially cause referred pain to the lower back.
Here are some key points to consider regarding your symptoms:
1. Hydration: It is crucial to maintain adequate hydration. Insufficient water intake can lead to concentrated urine, which increases the risk of kidney stones and urinary tract infections. Aim to drink plenty of water throughout the day, especially if you are experiencing pain.

2. Urinary Symptoms: If you are experiencing frequent urination, urgency, or pain during urination, these could be signs of a urinary tract infection or bladder irritation. It is essential to seek medical attention if these symptoms persist.

3. Pain Characteristics: Pay attention to the nature of your pain. If it is sharp, sudden, and accompanied by other symptoms such as fever, chills, or changes in urine color, it may indicate a more serious condition that requires immediate medical evaluation.

4. Posture and Activity: Consider your posture and physical activity levels. Poor posture while sitting or standing can lead to muscle strain in the back, which may mimic kidney pain. Incorporating regular movement and ergonomic adjustments in your workspace can help alleviate discomfort.

5. Medical Evaluation: Given your symptoms and the potential for kidney-related issues, it is advisable to consult a healthcare professional. They may recommend imaging studies, such as an ultrasound or CT scan, to assess the kidneys and urinary tract. Blood tests, including kidney function tests and urinalysis, can also provide valuable information.

In summary, while your symptoms could be related to kidney issues due to dehydration and urinary habits, they could also stem from musculoskeletal problems. It is essential to address your hydration and urinary habits while seeking medical advice to determine the exact cause of your pain. Early intervention can help prevent complications and improve your overall health.
