First of all, it must be said that most people absolutely incorrectly localize the place where, in their opinion, painful changes in the kidneys occur. If the patient feels pain in the back or side, this does not mean that his kidneys exactly hurt, because they are located much higher than the waist, immediately below the lower ribs.
Symptoms that accompany kidney pain
It is possible to say that the kidneys are sore, and not something else, if the soreness of this organ is associated with the predicted symptoms of the disease. So, for example, for the infection process inside the kidneys, a dull, aching pain is characteristic, which is localized only on one side of the body. In addition, most infectious diseases of the kidneys will be characterized by a violation of the normal function of urination and a significant increase in temperature.
By the way, many people think that with urolithiasis the kidneys are very sore , this is not so. Kidney stones do not bother the patient at all until they begin to be excreted through the urinary canals. It is the passage of stones into the bladder through the ureter that is accompanied by severe pain of a spastic nature, which is also called renal colic.
Reasons for kidney pain
Pain in the kidney can be caused by a number of diseases that will affect the normal functioning of this organ, in particular, severe pain in the kidney occurs with atherosclerosis of the renal artery, which causes blood clots or the effect of renal tissue ischemia. In addition, kidney pain occurs with renal bleeding, hydronephrosis or polycystic kidney disease, with any urinary tract infection and with renal vein thrombosis, that is, with the formation of small blood clots in the veins of an organ.
Another common disease in which the kidneys hurt is pyelonephritis. In this case, the disease has an infectious nature and leads to swelling of the organ, which affects the stretching of the capsule, which causes pain. With pyelonephritis, since it is an infectious disease, the kidneys are sick and the temperature is elevated, nausea and vomiting can also be observed. Pyelonephritis requires immediate treatment, because there is a high risk of complications if infectious agents enter the general bloodstream.
Diseases in which pain in the kidneys is mild
With kidney cancer in the initial stage, there is practically no severe pain in the kidneys - this is due to the fact that the disease develops for a rather long time, and the tumor stretches the capsule of the organ, which is the source of pain, gradually, therefore the cancer cannot make itself felt with acute pains .
With polycystic kidney disease , an extensive increase in the kidney is observed over many years, therefore this disease also cannot cause sharp pain in the kidneys, but only gives a mild dull and aching, which occurs due to the stretching of the renal capsule.
When to see a doctor
Often there are cases when the kidneys are sore after alcohol - not every doctor will decide to make an accurate diagnosis, but for what pain should you immediately seek medical help? First of all, you should seek medical help if the pain in the kidneys lasts several days and has associated symptoms such as fever, recent infections, aches and tiredness throughout the body. You should also go to the doctor if you find blood in the urine, because this can be the cause of a wide variety of diseases, from simple kidney injuries to serious oncological diseases, which are best to be treated in the early stages of occurrence.
