To confirm underlying issues, additional tests may include: - Urinalysis: Checking for infection, blood, or other abnormalities - Blood tests: To evaluate kidney function or signs of infection - Imaging studies: Ultrasound, CT scan, or MRI to visualize kidney structure and detect stones, cysts, or other abnormalities - Further diagnostics as needed based on initial findings

Treatment Protocols: Management of conditions causing CVA tenderness varies depending on the underlying diagnosis. Typical approaches include: - Antibiotics for infections such as pyelonephritis - Pain management strategies with NSAIDs or other analgesics - Hydration therapy to facilitate passage of kidney stones - Surgical intervention in cases of large stones, structural abnormalities, or persistent issues - Addressing musculoskeletal causes with rest, physical therapy, or other supportive measures It’s essential to seek medical attention if you experience persistent flank pain or tenderness, as early diagnosis and treatment can prevent complications.
