My Husband recently started taking lysinopril for HBP, and shortly after, ,started having a burning sensation in his chest. When He went to see his physician the blood work and urinalysis showed he was having renal failure?? He had had no symptoms of kidney problems. They immediately took him off lysinopril and had him back in the office the next day for more test, the Dr. stated he had expected to admit him to the hospital but that the new test showed much improvement. Can this be possible or is it more likely the org. test were wrong?
