I am 37, have gerd and had my gall bladder removed 5 years ago. Over the past few months, my night time heartburn has been so bad that on 3 occasions I have woken with acid in my sinus and mouth. I honestly thought I was going to drown. Currently, I am slowly recovering from what I think was the stomach flu (vomiting, diarrhea, heartburn, body aches). This is the first day in six days that I have been able to eat. Now that I have eaten, there is a lump in my throat that is making it difficult to swallow. Is this just irritation from acid, or should I be worried?
