Denied

I just received a denial letter for hemorrhoids. Said not service connected. I was in Desert a Shield/Storm for almost a year. I developed hemorrhoids a few months into the deployment and saw the medics and was given hemorrhoid cream and told to take it easy. My medical records do not show the visits I made to the medics.

I have had 6 hemorrhoid surgeries since and have flare ups constantly. My civilian medical records show all of this dating back to when I got out. What can I do to show service connected?
