My father Lt Col IS Rawat (retired), 97 years old,suddenly developed swelling on his left toe. The color of the swollen area was much like the image in this site. It was followed by excruciating pain during the night. Next morning I gave him ACV, one teaspoon in one glass of filtered water. Within 24 the redness, swelling & pain was gone. He is comfortable & has since shown no sign of any more symptoms of gout. The dosage of ACV continues.
