If itching becomes severe, widespread, or continues despite normal skin care, medical evaluation can help identify the underlying cause.
- Muscle Cramps
Unexpected muscle cramps—particularly in the legs—can have many causes.
Dehydration, intense exercise, certain medications, and electrolyte disturbances are common possibilities. Kidney problems can also affect the body’s balance of minerals and electrolytes.
Frequent or severe cramps, especially when accompanied by other symptoms, should be discussed with a healthcare professional.
- Changes in Urine Color
Urine naturally changes color depending on hydration and other factors.
Dark yellow urine often simply means you need more fluids. However, red, pink, brown, or unusually dark urine can sometimes indicate blood or another medical issue.
Certain foods and medications can also change urine color.
If you notice unexplained blood in your urine, seek medical advice rather than assuming it will disappear on its own.
- Persistent Lower Back or Side Pain
The kidneys are located toward the back of the upper abdomen, underneath the lower ribs.
Certain kidney conditions can cause pain in the side or back, particularly when accompanied by fever, nausea, urinary changes, or painful urination.
