If you experience back pain near kidney area it may indicate one of two possible disorders (or both): either spine and back muscle disorders or kidney disease. The most common kidney disease is renal colic and pyelonephritis. Usually if you experience lower back pain near kidney area it may be a symptom of kidney disease. When the acute renal colic occurs there is painful lower back pain usually pays in the groin, leg, or genitals. The attack is accompanied by nausea, vomiting, flatulence and urination disorders.
In the case of urolithiasis attack, renal colic may occur without any apparent cause; and if there is nephroptosis (omission of the kidneys), it is provoked by prolonged walking or physical stress. The attack lasts for several hours and after is there is a dull pain in the lower back that stays for a pretty long time. Sometimes this pain extends to the whole abdomen which in combination with dyspepsia may be mistaken for disease of the digestive system, for example, duodenal ulcer, cholecystitis, or intestinal obstruction.
One can identify renal colic can only observing the troubled behavior of patients and the absence of increasing severity of symptoms (plus data from analysis). The colic is characterized not only by a sudden onset of an attack, but by the sudden end as well. Treatment is only stationary; it is impossible to treat colic at home.
Pyelonephritis (kidney inflammation) may be called simply a mass disease, especially in its chronic form. Acute pyelonephritis has several forms, but they all begin acutely, with a high temperature to 40 degrees of Celsius, chills, drenching sweat, low back pain and muscle tension of the abdominal wall from the side of the diseased kidney. If the left kidney is affected, the pain is felt in the upper back on the left side, and if the right – then in the upper right side of the back.
Sometimes it is a bilateral pyelonephritis, when a fever and back pain come along, there is growing malaise, thirst and urination disorders. In acute pyelonephritis there is often a headache, nausea and vomiting, which indicates the presence of intoxication. Treatment is also stationary, because there may be serious disease complications.
Chronic pyelonephritis may remain after acute pyelonephritis or proceeds without acute symptoms from the beginning of the disease. Most patients with chronic pyelonephritis experience it from their childhood, especially girls. The main symptoms of it are the periods of unexplained fever and a constant dull or throbbing pain in the lower back on the side of the affected kidney, or both sides.
During periods of exacerbation of chronic pyelonephritis only one fifth of patients have fever; the more frequent symptom is a high blood pressure. Accurate diagnosis is possible by specific diagnostic tests, although sometimes it is not easy to perform because of the variety of forms and stages of the disease, where the tests are mutually exclusive. It is easy to identify pyelonephritis in patients with a clear clinical picture, but there are not so many of such cases.
Meanwhile, the disease requires careful attention and proper treatment, because it may lead to irreversible changes in the kidneys and severe consequences. Treatment should be prolonged enough; sometimes it takes years to complete it. There is a class of drugs for the treatment of kidney and whole urinary system – UB antiseptics. If necessary, UB antiseptics are combined with broad-spectrum antibiotics to suppress the bacteria that cause inflammation of the kidneys. With timely and appropriate treatment one can achieve long-lasting remission (a period without any symptoms of the disease) and maintain renal function at normal levels.
