Is back pain a symptom of kidney failure?

Patient's question:

I've been feeling lower back pain recently, it might be because I'm tired. It's said it could be kidney failure. I wonder if the lower back pain is kidney failure?

Doctor's answer:

Lower back pain doesn't necessarily indicate kidney failure. There are many reasons for lower back pain. For example, lumbar muscle strain or a herniated intervertebral disc can cause lower back pain. Patients with kidney failure may also experience lower back pain, but it is not the most prominent symptom. The most prominent symptoms are hematuria and edema. Proteinuria and anemia. Generally, the stage of kidney failure is similar to uremia. Although the damage is already severe, pain is normal. Kidney failure is a manifestation of functional decline after kidney damage. When discussing kidney failure, the symptom of lower back pain will certainly reappear because the kidney damage is relatively severe at this point. Additionally, kidney failure also manifests as hematuria, proteinuria, edema, anemia, etc. It is essential to pay attention to exercise regularly.
