3) Difficulty, Pressure Or Pain During Urination: This can be a symptom of urinary tract infection – note also fever or lower back pain in the kidney area.
4) Unusual Urinary Function: Be on the lookout for significant changes in your urination pattern – for example increase or decrease in frequency and/ or amount – especially during the night. Difficulty in urination is also a sign, as is dark colored urine.
5) Fluid Retention (Fluid Volume Overload): As the kidneys flush waste from the body, loss of kidney function can mean fluid retention / edema. This could range from mild edema to life-threatening pulmonary edema.
