Kidney problems


Hello doctor, I previously asked a question regarding experiencing pain when turning over and feeling a lump, which seemed to be intermittent.
My urination was normal at that time.
Now, those issues have resolved, but I have noticed swelling in the kidney area, and I cannot feel any lumps.
What could this problem be?

Regarding the swelling in the kidney area, if there are no palpable masses, it is still advisable to consult a physician for further evaluation.
An ultrasound examination can be arranged for confirmation and peace of mind.
Thank you for your inquiry.

Hello! It sounds like you're experiencing some concerning symptoms related to your kidney area, and it's important to address these issues thoroughly. Based on your description, you mentioned that you previously felt pain when turning over and noticed a hard lump, but now those symptoms have subsided, and instead, you are experiencing swelling in the kidney region without any palpable mass.
Firstly, it's essential to understand that the kidneys are located in the retroperitoneal space, which means they are situated behind the abdominal cavity. Swelling in this area can be due to various reasons, including fluid retention, inflammation, or even underlying kidney disease.
One possible explanation for the swelling could be related to fluid accumulation, which might occur due to conditions such as nephrotic syndrome, where the kidneys leak protein into the urine, leading to low protein levels in the blood and subsequent fluid retention. Another possibility is that there could be an obstruction in the urinary tract, leading to hydronephrosis, which is the swelling of a kidney due to a build-up of urine. This can happen if there is a blockage in the ureter or if there are kidney stones present.

Additionally, if you have a history of kidney issues or other systemic conditions, such as hypertension or diabetes, these could also contribute to changes in kidney function and swelling. It's also worth noting that certain medications can affect kidney function and fluid balance, so if you are on any medications, it would be wise to review these with your healthcare provider.

Given that your previous symptoms have changed, it's crucial to seek further evaluation. A healthcare professional may recommend imaging studies, such as an ultrasound or CT scan, to assess the kidneys and surrounding structures for any abnormalities. Blood tests to evaluate kidney function (such as serum creatinine and blood urea nitrogen) and urine tests to check for protein or blood in the urine would also be beneficial.

In summary, while the absence of pain and hard lumps may seem like an improvement, the new swelling in the kidney area warrants further investigation. It's essential to consult with a healthcare provider who can perform a comprehensive evaluation and determine the underlying cause of your symptoms. Early diagnosis and management are key to addressing any potential kidney issues effectively. Please make sure to follow up with your doctor for a thorough assessment and appropriate care.
