You could possibly die. Or have sharp pain. I would see a doctor if I were you.

You can get chemical burns along your throat and stomach if you swallow lye.
If you swallow a toothpick, you should contact a medical professional.Swallowing a sharp piece of a wooden toothpick is a common occurrence. However, in a number of cases it has proven to cause serious internal injuries. The pick can lodge in the digestive tract, blocking food flow, or even perforate the esophagus, trachea, stomach, or intestinal wall, with the potential for bleeding or infection. This can be more dangerous to babies or children.Children should never be alllowed to play with toothpicks, especially plastic ones that cannot soften as wooden ones might if ingested.
You burp bubbles
It depends on how much you swallow. If it is a large amount, you could get diarrhea and/or vomit.
This too will pass.
