Kidney Pain: Causes and Concerns for Your Health

The kidneys are not functioning properly?

Hello, doctor: Recently, when I wake up at night after deep sleep, I sometimes feel pain in my right lower back.
A slight movement makes me feel very uncomfortable, and the pain intensifies.
I'm wondering if there might be an issue with my kidneys.
Additionally, after waking up at night feeling the urge to urinate, I experience a sensation of bloating in my stomach, as if the urine is flowing into my stomach, which is uncomfortable (standing is much more comfortable than lying down).
In more severe cases, not only do I feel bloated in my stomach, but I also feel a bloated sensation in the kidney area.
I suspect that urine might be refluxing into my kidneys, which could be causing this bloated feeling.
I'm unsure whether the issue lies with my bladder or my kidneys.
Could you please help me address these two concerns? Thank you, doctor, for your attention to my questions.

It is recommended to visit the urology department for further examinations, such as urine tests and X-rays.
Generally, the urinary system does not cause gastrointestinal discomfort, so it is important to clarify whether there is a true correlation between the two.
Otherwise, it may mislead the physician in making a diagnosis.
If there is a urinary system issue, urine tests or specialized urodynamic studies can assist in diagnosis.
Based solely on these descriptions, it is not possible to determine if it is a urinary disease.
Please go to the hospital for further examination and allow the physician to conduct a physical examination.

Understanding kidney pain can be complex, as it may stem from various causes, including issues related to the kidneys themselves or other structures in the body. Based on your description of experiencing pain in the right lower back, particularly when moving, and the sensation of abdominal bloating or discomfort, it is essential to consider several potential factors.

Firstly, the pain you are experiencing in your lower back could be related to musculoskeletal issues rather than a direct kidney problem. The kidneys are located towards the back of the abdomen, and pain in this area can often be confused with discomfort originating from the muscles, ligaments, or spine. Conditions such as muscle strain, ligament sprains, or even spinal issues like herniated discs can cause similar pain. If the pain worsens with movement, it may suggest a musculoskeletal origin.

However, it is also crucial to consider kidney-related issues. Kidney pain is often described as a deep, aching sensation that may radiate to the lower abdomen or groin. If there is a concern about kidney stones, infections, or other renal conditions, these can also present with pain in the lower back. For instance, kidney stones can cause severe pain, often described as sharp or cramping, and may be accompanied by other symptoms such as hematuria (blood in urine), nausea, or vomiting.

Regarding your concern about feeling bloated or having a sensation of urine flowing back into the stomach, this could indicate a urinary tract issue. Normally, urine flows from the kidneys to the bladder and then out of the body. If there is a blockage or dysfunction in this system, such as a urinary tract infection (UTI) or bladder dysfunction, it could lead to discomfort and a sensation of fullness. In some cases, conditions like hydronephrosis, where urine backs up into the kidneys due to an obstruction, can cause swelling and pain in the kidney area.

Given these symptoms, it is highly advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, including a physical examination and potentially imaging studies such as an ultrasound or CT scan, to assess the kidneys and surrounding structures. Additionally, urine tests can help identify any signs of infection or other abnormalities.

In summary, while your symptoms could be related to kidney issues, they may also stem from musculoskeletal problems or urinary tract dysfunction. It is essential to consult a healthcare professional who can provide a comprehensive assessment and appropriate diagnostic tests to determine the underlying cause of your symptoms. Early intervention can lead to better outcomes and help prevent potential complications. Remember, your health is paramount, and addressing these concerns with a medical professional is the best course of action.
