1. Kidney stones
The presence of kidney stones causes the onset of severe pain that may be directed to the belly or genital organ, pain when urinating, and pink, reddish or brown urine due to the presence of traces of blood.

How to treat: Drink plenty of water to help eliminate the microorganism causing pain and make use of antibiotics, according to the guidance of the general practitioner or urologist.
3. Polycystic kidney or cyst
Symptoms of cyst in the kidney only appear when the cyst is already large, and can cause pain, urine with blood, high blood pressure and frequent urinary infections.
How to treat: Treatment should be recommended by a nephrologist and can be done with the use of medications, when the cyst is small, or through surgery, which is done to remove the larger cysts.

It is the swelling of the kidney due to the accumulation of urine, causing pain in the back, urine with blood, fever and chills.
How to treat: You should go to the doctor to remove the accumulated urine and identify the cause of the problem, which may be kidney stones, severe urinary tract infection or kidney tumor. See more in: Hydronephrosis.
6. Renal vein thrombosis or ischemia
That's when there is not enough blood for the kidney, causing cell death and pain. It is similar to what happens in stroke or when you have a heart attack.

Kidney pain in pregnancy
Kidney pain in pregnancy is usually caused by changes in the spine, due to the effort that the pregnant woman makes by the weight of the belly. Rarely it is related to renal changes, but in cases that there is also pain when urinating, one should consult the gynecologist to identify the cause of the problem and to avoid complications.
To relieve it, you can place a hot water bottle in the painful region and lie back in a comfortable armchair, with feet elevated. This position relieves back pain and dislodges the feet. See more in: Kidney pain in pregnancy.
When to go to the doctor
It is recommended to seek medical help whenever the pain in the kidneys is very strong, preventing the normal routine activities, or when the pain becomes frequent. Although there are many causes of kidney pain, it can often also be related to spinal problems, and so physical therapy may also be a treatment option.
