Why do patients with chronic renal failure (CRF) suffer from severe pain? Chronic renal failure (CRF) is a complex kidney disease that affects well other systems and organs. Some patients with CRF suffer greatly from severe pain, for example, headache, pain in the legs and back.

- Headache and chronic renal failure:

Kidneys not only cleanse blood, but also regulate blood pressure. When the kidneys do not function, the pressure rises and the blood circulation deteriorates. And this directly causes a headache. In addition, renal anemia is a common complication of CRF and also worsens the headache.

If patients with CRF are already on hemodialysis, then headache may have a connection with low blood pressure and electrolyte imbalance.

- Headache and chronic renal failure:

When the kidneys are not able to work properly, excess fluid accumulates in the body and causes swelling in the legs. In most cases, the legs swell, but in severe cases, pain in the legs occurs. Moreover, low calcium and high phosphorus also cause pain in the legs.

- Pain on the back and CRF:

Typically, pain on the back occurs with polycystic kidney disease, IgA-nephropathy and diabetic nephropathy.
