Hello, my name is Frank you may have seen me around, I have a problem...

I keep getting these stomach pains, it's like really bad indigestion but has been happening on and off for days. A few questions:

1) What could be causing them?
2) How do I make them go away?
3) Is there any relevance in the fact I was on a huge bender over the bank holiday weekend? - they started after that.

Thanks.
