Cola or dark brown-coloured urine, especially associated with left back pain and weakness, is a significant symptom that should not be ignored even though it has now resolved. The most likely explanation in your case is a kidney stone — a stone in the left kidney/ureter can cause left back pain, blood in the urine (which turns it dark/cola-coloured), and general weakness. Drinking more water may have helped flush the stone or reduce concentration, which is why the colour normalised. Another important cause to consider is Rhabdomyolysis — breakdown of muscle tissue that releases a protein (myoglobin) into the blood and turns urine dark — this can follow strenuous physical activity, fever, or an illness. Even though your urine looks normal now, the underlying cause has not been identified. It is essential to get tests done: urine routine and microscopy (to check for blood/protein in urine), kidney function test (KFT/serum creatinine), urine culture, and a USG abdomen to look for kidney stones. This should not be left uninvestigated.

Cola colour urine (or dark brown) urine is most commonly caused by many reasons. Some among them are kidney disease, - kidney stone/ UTI/ interstitial severe dehydration, liver issues (like hepatitis or cirrhosis), or extreme muscle breakdown (Rhabdomyolysis) Bleeding disorder Certain foods Injury somewhere in urinary tract etc etc.. Get your urine routine examination to know whether it's blood or something else.
