I Am 64 Years Old An Woke Up In The

i am 64 years old an woke up in the middle of the night with a burning in my throat like heartburn that comes and goes and this morning i started having diahreaa. The diahreaa has subsided somewhat but i get that terrible burning about once every 30 minutes and it lasts about 10 minutes and my stomach feels queasy. I have had had jello and 1/2 banana to eat today. Nothing out of the ordinary yesterday and felt fine when I went to bed. Right now I feel terrible.
