due to the fact that you have tried some over-the-counter medications and it has been three days and you do not have any relief not able to drink or eat anything (and still severe pain) i would strongly recommend calling your doctor or health care provider as soon as possible or go to the er to have it checked out. this could be a sign of something serious.
i’ve had heartburn for three days cannot eat or drink anything without severe pain. nothing works. what do you suggest?
