Every person feels pain in different ways and in different places. Different people respond to pain in different ways. This information area is not designed make a diagnosis in your case. A diagnosis must be reached on an individual basis with your own doctor. You are probably reading this because you think pain is coming from your kidneys or urine. This may not be the case - your pain could be due to something else entirely. Please use this section to understand some of your symptoms and to cope with them. If a diagnosis is made by a doctor, then the NKF hopes this website can help with further information on your own diagnosis.
Pain is the main way that our body tells us something is wrong. Pain is one of the commonest reasons that makes someone go to see a doctor for suspected problems with the kidneys or urine.
Unfortunately everything is not as simple as might be expected. First, most of the important causes of kidney failure do not cause any pain in the kidneys. Secondly, not all pains that come from the areas of the kidneys mean that there is a problem with the kidneys. When assessing someone with pain, a doctor has to be careful and may need to perform at lot of tests which can take some time. Even after tests, a doctor may not be absolutely sure of the cause of pain. Of course this can be difficult for the person suffering from pain.
People use different words to describe pain - aching, stabbing, excruciating, agonising and so on. This information section will not use these terms, but the writers do know that pain can be very unpleasant. What doctors want to know about pain is:-

Pain can come from any part of the kidneys and urine drainage system. The next few paragraphs try to describe how pain occurs with various types of kidney problem. Please remember that everyone is different, so that people feel pain in different ways and in different places. Also, peoples’ bodies and minds respond to pain in different ways.
The kidneys are found in the upper back (the ‘small of the back’, it is often called). Kidney disease can cause pain in this part of the upper back. Pain in this area is common, and often comes from the muscles of the back, or from the spine. Pain from the kidneys is often constant, or can be sharp, like being stabbed. Pain from the muscles or the spine comes on with bending over or with lifting, and may be felt in the middle of the back, rather than on either side over the kidneys.
The commonest causes of kidney pain in the back are infection (an infection in a kidney is called acute pyelonephritis), and kidney stone (which can cause a very, very severe pain that comes on in spasms, and travels down to the groin, and is called renal colic by doctors).
The body feels pain in unusual ways, and sometimes pain from an internal organ is felt away from the site of the internal organ (the commonest example is pain from the gallbladder, in the tummy, which can be felt on the tip of the shoulder). The kidneys can be a little like this, so that pain in the kidney can be felt all the way from the back down to the groin, or in the testicles in men.
The testicles can also feel painful due to infection (this can be called orchitis or epididymo-orchitis).
The testicles can also enlarge or become painful due to other important conditions. One of these is testicular cancer, and advice should be sought from a doctor if a testicle (or both) is permanently painful, or increases in size.
A stinging pain in the tube (called the urethra) that carries urine out of your body (from the bladder) is a common symptom of urine problems. Infection is the commonest cause of pain that is present while urine is being passed, and might cause intermittent pain or itching in between passing urine.
The commonest cause of pain of this type is urine infection. If an infection is confined to the bladder there may also be urgency to pass urine frequently, and some pain in the front of the tummy, right down at the bottom. This type of infection, in the urine and bladder, is called cystitis. Bugs in the urine that cause infection can also make the urine foul smelling or cloudy.
Some painkillers purchased ‘over the counter’ at the chemists can be used for kidney pain.
Paracetamol is the safest painkiller if you have kidney pain. Do not take above the recommended dosage (one gramme - 1g or 1000mg - of the active ingredient, usually two tablets, four times a day).
If this is not effective, painkilling tablets containing codeine may be used.
If this is still not effective, talk to your doctor about painkillers. Unfortunately it is often difficult to get complete pain relief in people with severe kidney pain.
Some painkillers can be harmful in some people with kidney trouble. Ibuprofen is not generally recommended if there is any degree of kidney failure. Ibuprofen is also sold under the trade names ‘Nurofen’ and ‘Advil’. Only take ibuprofen for kidney pain if its use has been recommended by a doctor.
Doctors can investigate pain that seems to come from the kidneys with a number of tests. These are examples of the simple tests, but the needs of each person will be considered individually.
Some tests may also be performed to make sure the pain is not coming from the muscles or bones of the back, or from the bowel or gallbladder. It is not possible to list all these here.
Here is a brief summary of some of the causes of pain from the kidneys or bladder:-
Most people with kidney pain get better with treatment (eg treatment of infection or removal of a stone). However, some people do get long term (chronic) pain. Pain that will not go away is one of the worst medical problems anyone can have. There are a number of ways that someone can try to deal with pain. One is to have a satisfactory diagnosis and plan of treatment from a specialist. However, even with the help of drugs, a specialist cannot always get rid of pain. Therefore finding a strategy that helps you cope with the pain may be needed. This may require the help of a hospital pain specialist or a psychologist. Some people get relief from alternative therapies such as acupuncture. Click here for further advice on coping with long term pain.
