You said that you have had Acid Reflux Disease for two days and have tried to fix it but to no avail. I suggest you go to the doctor because it could be a host of things from intestinal blockage, internal bleeding, and a stomach virus. It could be  a truck load of reasons- both big and small.

If it's internal bleeding you can bleed to death. It could be kidney problems. As my mother use to tell me there's more room out than it is in. That is true of our bodies, for our internal plumbing is locked in our insides and when one organ or system is affected it may have a domino affect and knock down our other systems and organs.

I wish you a speedy recovery and many more years of life and if possible eternal life.
