Back pain: sciatica, or inflammation of the kidneys?

Few people unfamiliar sensation of pain in the lumbar region. Traditionally, this condition is associated with problems of the spine or back muscles, but many people do not even suspect how rich and complex is anatomically the lumbar region. Therefore, pain can be a symptom of diseases of the gastrointestinal tract, cardiovascular and urinary systems and many others.

Often have to distinguish between the two most common causes of lower back pain — diseases of the musculoskeletal system and kidney disease.

A common cause of lower back pain are sciatica, or degenerative disc disease of the spine. It diseases of the musculoskeletal system, so they will be enhancing or changing the character of the pain with movement or changing position of torso. In this it differs from the pain associated with kidney pathology — it is more or less constant and is not changed during movement.

The second important feature is back pain with kidney disease is the presence of associated symptoms:

  • increase in blood pressure and body temperature,
  • the presence of edema in the hands, legs, face (an important characteristic of these swellings is their presence in the morning after you Wake up and disappearing during the day),
  • change in urination (it may become frequent and painful, or on the contrary rare, up until his disappearance) and urine (it can be defined a residue to change its color, quantity).

In addition to the renal symptoms are signs of General intoxication:

  • lethargy,
  • drowsiness,
  • nausea,
  • vomiting,
  • depressed mood,
  • loss of appetite.

You also need to understand that no disease occurs by itself, it is always preceded by some precipitating its events. Lower back pain in diseases of the musculoskeletal system occurring after physical load on the spine (heavy lifting, prolonged standing position), sleeping in an uncomfortable position.

For kidney disease the same provoking factors, is:

  • General hypothermia,
  • recent sore throat,
  • inflammatory diseases of the genital organs.

Pain in the kidney disease is localized on one or both sides of the vertebral column and is able to radiate to the groin, inner thighs, anterior abdominal wall.

Characteristics of lower back pain kidney disease depends on the nature of the pathological process. Urolithiasis is possible to advance the so-called renal colic — this occurs when a small stone gets into the ureter. Muscles in the wall of the ureter try to push forward and spasticeski reduced, causing intense sharp pain that radiates to the area of the external genitalia. The stone blocks the flow of urine from the kidneys, it stretches and causes a less severe, dull pain in the lumbar region.

In inflammatory renal diseases (glomerulonephritis, pyelonephritis) the nature of the pain other — she is aching, constant, localized on either side of the spine. Pain syndrome is not as strong as with sciatica or osteochondrosis.

In order to finally find the cause of pain in the lower back can be the edge of his hand gently to gently tap on the back just below the rib cage — in inflammatory diseases of the kidneys such beating will cause a dull pain that radiates down the abdomen.

To distinguish the cause of pain in the lumbar region is extremely important as this determines treatment strategy.
