Hi, I ate dinner, coughed once, had a taste of alfalfa in my mouth and it felt like acid reflux. Went to clear my throat and spit and kept spitting out some blood. It is slowly clearing now but it definitely came from throat and not the sinuses or mouth. I had Lasagna, broccoli, tomatoes and yogurt. I did take some digestive and vitamin supplements before dinner and just after. I do get acid reflux once in awhile. Thank for your help!
