Muscle strain or kidney issues?
Five days ago, while swimming, I noticed some pain near my kidney area, similar to the soreness one feels after intense exercise, like sprinting 500 meters.
The next day, the pain intensified, but I didn't see a doctor at that time.
Over the past few days, the condition has improved; I don't feel pain when my body is at rest.
Walking doesn't cause much pain either, but I do feel a slight discomfort when I sprint.
Additionally, when I exert myself in my abdomen (for example, when using the restroom), I experience some pain on the left side near the kidney area.
Could this be a muscle strain, or is it a warning sign of an issue near the kidney? If I need to see a doctor, which specialty should I consult? I am generally healthy, rarely get sick, and have mild hereditary Mediterranean anemia.
Thank you for your help.

Hello: In response to your question, pain in the left back near the kidney can have many potential causes.
Common conditions include fasciitis, kidney stones, inflammatory arthritis, myofascial pain syndrome, neuritis, skin disorders, tumors, and vascular lesions, among others.
Based on your description, a muscle strain may be suspected, but other possibilities cannot be ruled out.
Therefore, it is advisable to discuss this with your primary care physician before making any decisions.

More Info
When it comes to pain in the area near the kidneys, distinguishing between muscle strain and potential kidney issues is crucial. Based on your description, it seems that the pain you are experiencing is likely related to muscle strain rather than a kidney problem. However, it is essential to consider various factors to arrive at a more definitive conclusion.
Muscle strain typically occurs when the muscles are overstretched or torn, often due to sudden movements or excessive physical activity. In your case, swimming could have caused a strain in the muscles surrounding the lower back and abdominal area, particularly if you engaged in vigorous strokes or movements that your body was not accustomed to. The fact that the pain intensifies with specific movements, such as running or exerting pressure during activities like using the restroom, supports the idea of a muscle strain.
On the other hand, kidney-related pain often presents differently. Kidney pain is usually felt deeper in the back, often on one side, and may be accompanied by other symptoms such as changes in urination, fever, or nausea. Since you mentioned that your pain does not worsen with walking and only appears during specific movements or exertions, it leans more towards a muscular issue. Additionally, if you were experiencing kidney problems, you might also have symptoms like pain during urination or changes in urine color, which you have not indicated.
Given your history of mild hereditary Mediterranean anemia, it is also worth noting that while this condition primarily affects blood and does not directly relate to kidney function, maintaining overall health is essential. Staying hydrated and managing your diet can help support your kidney health, especially if you have any underlying conditions.
If the pain persists or worsens, it would be wise to consult a healthcare professional. In this case, you should consider visiting a primary care physician or a sports medicine specialist. They can perform a thorough examination, possibly including imaging studies like an ultrasound or MRI, to rule out any serious issues. If necessary, they may refer you to a urologist if there are any concerns regarding kidney function.
In the meantime, here are some recommendations to manage your symptoms:
1. Rest: Allow your body to recover by avoiding activities that exacerbate the pain.
2. Ice Therapy: Applying ice to the affected area can help reduce inflammation and alleviate pain.
3. Gentle Stretching: Once the acute pain subsides, gentle stretching and strengthening exercises may help improve flexibility and prevent future strains.
4. Hydration: Ensure you are drinking enough water, as hydration is vital for overall health and can support kidney function.
5. Pain Relief: Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage pain and inflammation.
In conclusion, while your symptoms suggest a muscle strain, it is always best to err on the side of caution. If you have any doubts or if your symptoms change, seeking medical advice is the best course of action. Early intervention can help prevent complications and ensure a swift recovery.
