I Was Eating Sunflower Seeds Two Nights Ago And (stupidly

I was eating sunflower seeds two nights ago and (stupidly enough) managed to swallow a sliver of one of the shells among the seeds. Now, two nights later, I can still slightly feel it in my throat. It's near the bottom of my throat near my collarbone. I've had two slices of bread hoping they'd push it down along with them. But I've also been eating regularly since it happened. So I guess it should've already come out by now. Is there anything else I can do to get it to go down/come out, without having to go to the doctor?
