What Causes The Feeling Of Food Stuck In Throat Along With Irritation?

Few days ago I was making a smoothie. After I have consumed it I realised that there is something stuck inside of my throat. I'm assuming it's a bit of a pineapple, maybe the skin from the fruit which is hard and sharp. It's been like 3-4 days since the accident and I can still feel it inside my throat. It's irritating and hurts. I have made myself sick twice (intentionally) because I though that I would puke it out. Whatever it is still there. I don't know what to do. Should I go to the hospital? I'm scared that even if they were to do an xray it won't show anything and they won't be able to help me.
