I Have Ingested Something That Feels Stuck In My Throat.

I have ingested something that feels stuck in my throat. It really only bothers me when i swallow. Ive tried to throw up to get it unstuck but my mom says the only thing that will get it out is coughing which isnt working. Its been stuck almost a week now & is starting to hurt. Im not sure if its stuck at the opening of my esophogus or my wind pipe. What can I do?
