Yes, your body can ache with kidney disease, often presenting as muscle cramps, general body aches, bone pain, and joint pain, especially as the condition progresses, due to fluid/mineral imbalances and related complications like anemia or mineral bone disorder. While early stages might have no symptoms, later CKD often leads to fatigue, swollen limbs, and musculoskeletal discomfort.
Where do I feel kidney pain? You feel kidney pain near the middle of your back, just under your ribcage, on each side of your spine where your kidneys are. Your kidneys are part of the urinary tract, the organs that make and remove urine from the body.
Generally, earlier stages are known as 1 to 3. And as kidney disease progresses, you may notice the following symptoms. Nausea and vomiting, muscle cramps, loss of appetite, swelling via feet and ankles, dry, itchy skin, shortness of breath, trouble sleeping, urinating either too much or too little.
Severe loss of kidney function causes metabolic wastes to build up to higher levels in the blood. Damage to muscles and nerves can cause muscle twitches, muscle weakness, cramps, and pain. People may also feel a pins-and-needles sensation in the arms and legs and may lose sensation in certain areas of the body.
Kidney pain is usually deeper, higher up under the ribs on the sides (flank), constant, and may come with fever, chills, nausea, or urinary changes; while general back pain is often lower, more superficial (muscles/spine), changes with movement, and may improve with rest, but watch for radiating pain down the leg (sciatica) or numbness.
Dull or sharp pain in the low back (often confused for kidney pain) is more likely due to a muscle pull, spinal issue, such as sciatica, or an injury. Kidney pain is usually felt higher up in the back and very rarely that low.
Three key early warning signs of kidney problems are changes in urination (more or less frequent, especially at night), foamy or bloody urine, and persistent swelling, particularly around the eyes, feet, or ankles, indicating fluid retention. Other common signs include persistent fatigue, nausea, itching, and loss of appetite, as toxins build up when kidneys aren't filtering effectively.
CKD patients show a significantly slower gait speed that is associated with physical [19–22], cognitive [23], sensory [24] and metabolic [25, 26] capacities, factors that are all influenced by CKD severity.
You can check kidney function at home using at-home test kits for urine (detecting protein/albumin) or finger-prick blood tests (checking creatinine/eGFR), often with smartphone apps for analysis, or by monitoring symptoms like increased nighttime urination (nocturia), swelling, or changes in urine (blood, foam) and discussing results with a doctor, as home tests screen but don't replace professional diagnosis.
Fluid retention, swelling (edema) of extremities and shortness of breath: Urination changes (foamy; dark orange, brown, tea-colored or red if it contains blood; and urinating more or less than normal) Kidney pain felt in their back. Sleep problems due to muscle cramps or restless legs.
Diabetes and high blood pressure are the top culprits damaging kidneys most, as they harm the delicate filtering blood vessels, leading to chronic kidney disease (CKD) and failure; other major factors include smoking, obesity, dehydration, poor diet (high sugar/salt/red meat), certain medications (NSAIDs), lack of sleep, and genetic conditions. These factors create a cycle where damaged kidneys worsen blood pressure, further damaging them.
For thousands of years 'fishy' smelling breath and urine have been associated with renal disorders. This smell is now known to be caused by the presence of unusually high concentrations of amines. Some amines are exogenous volatile organic compounds (VOC) that are ingested as part of normal diet.
Consistently clear, colorless urine may indicate a person is over-hydrating or a potential dysfunction in the kidneys. Healthy urine is pale-to-light yellow color and may appear almost clear at points.
Key facts. Kidney pain is usually felt in your back or side and may spread to your groin. It can be caused by kidney stones, kidney infection or other kidney or urinary tract problems. The cause of kidney pain can be diagnosed with blood tests, urine tests and an x-ray, ultrasound or CT scan.
The main test for kidney disease is a blood test. The test measures the levels of a waste product called creatinine in your blood. A doctor uses your blood test results, plus your age, size, and gender to calculate how many millilitres of waste your kidneys should be able to filter in a minute.
Kidney Disease
Symptoms can include: weight loss and poor appetite. swollen ankles, feet or hands – as a result of water retention (oedema) shortness of breath.
Decreased kidney function can lead to sodium (salt) retention, causing swelling in your feet and ankles. Swelling in the lower extremities can also be a sign of heart disease, liver disease and chronic leg vein problems.
To strengthen your kidneys, focus on a healthy lifestyle: stay hydrated with water, eat a balanced diet low in salt and processed foods, exercise regularly, maintain a healthy weight, and avoid smoking and excessive alcohol, while also managing blood pressure and blood sugar to prevent damage.
Fatigue is among the most common and most distressing symptoms for patients with kidney disease (26), who may experience more fatigue than healthy people as early as CKD stages 2–3.
Dizziness and Trouble Concentrating
Anemia that is the result of kidney failure means that your brain is not getting enough oxygen, which can lead to memory problems, trouble with concentration, and dizziness.
Surprising Things That Can Hurt Your Kidneys
There's no medicine that can cure CKD, but medicine can help control many of the problems that cause the condition, the complications that can happen as a result of it and keep the kidneys working for longer. You may need to take medicine to treat or prevent the different problems caused by CKD.
