Metformin is not usually used in patients with impaired kidney function. The impaired function shows as elevated levels of urea and creatinine in blood, not acid accumulation on kidneys. Wish you good health!

Yes, if you are taking Metformin and your kidney function gets worse in the mean time, accumulated Metformin can cause a rare, but deadly complication due to severe lactic acidosis. Likely, your blood test showed worse metabolic acidosis so your doctor told you to stop Metformin at once. You seem fine with this communication so if you already stopped Metformin that deadly complication won't occur.
