I think i've swallowed a fish bone, what can i do?

I agree with Frank, but in my position, I can only tell you to drink 2-3 almost full mouthfuls of water or juice, this should wash away any harmful substances that just might happen to be sitting there... But, like he said, if worse comes to worst, you AREN'T going to choke, you would only choke if something was totally blocking your air ways.. Also, drink milk from a bowl, like as if you have just finished some cereal and don't want to waste the milk, I have found that this remedy always works for just this..
