I Woke Up With A Very Dry Mouth, Like My

I woke up with a very dry mouth, like my mouth was hard. I drank water and it was fine, but I'm pretty thirsty, more then usual. A few hours later I got these horrible shooting pains in my abdomen, mostly lower left.it felt like I was being stabbed. Now I have a weird but not super painful stomach ache and I feel like I'm about to gag any second. I ate a good and filling breakfast so I know I'm not hungry or anything. But I did do a pretty intense workout about 3 days ago I don't know if that's the cause.
