What Is The Treatment For Swallowing Plastic?

I was making rice crispie treats, something I had never made before. I was using a sturdy plastic spoon on the mixture and as I snuck a tiny bite I noticed a strange texture. I pulled out a small piece of melted plastic from my mouth but not before swallowing a little bit. I only swallowed a small mouthful but I felt ill right away (not sure if from the plastic or from my own panic and nerves.) I could only make myself throw up a small amount. I'm feeling a little better now, but am wondering if I need to go to a doctor.
