at 5 am this morning, i woke up with indigestion like symptoms, in my lower middle chest and stomach, and it would move around and also to my back. It lasts for about 10 mins. then goes away, i have taken tums, but don t think it is my stomach. This happened about a month ago, about 12 midnight while in bed, can you suggest what it might be, or what i should do. It is the weekend and my doctor is away. Thank you.
