Nervous-Something in my thorat?

I had lamb for dinner. While eating it, i felt something stuck in my thorat. I have drank water, bread, wont go away. Almost like when you eat popcorn and get that piece in your thorat. But i hate this feeling because i get nervous i will choke on it.. What should i do?? im also nervous because i took out the lamb this morning to defrost at 8am. i ate it at 7pm. I never put it back in the fridge because it was frozen. my parents said its ok to eat but im nervous im going to get sick. my stomach feels weird... im nervous
