I was just simply stating what he was told, it was by all means a hypersensitive reaction which doctors often call allergic reactions as they did in his case. His nephrologist said he had never seen a reaction/flush this severe and ventured that it was a severe allergic reaction. Whether it was caused to his decreased renal function, or something else, it almost cost him his life. I simply stated as he was told.
I do agree doctors are in the business for money and they live off of fear, fear is what makes them rich. In all my years working in the health field I have never seen a niacin reaction/flush as bad as what my grandfather experienced.
