I have a problem with my intestines?

My bottom left side of my intestines have been bothering me all day. It seems like they could be bruised or something. I tried peeing a lot but thats not the problem. I kept drinking beverages all day just to see if it would quit but it hasnt. Now it seems that im having a problem with my troat to. I swollow just fine. It just seems like something is trying to come up and I have this weird taste in my mouth everytime I burp. The first time I burped it burned. I just wanted to see if anyone could figure out the problem so I dont have to go to the doctors if its not serious.
