I Had A Choking Experience Today, In Which I Tried

I had a choking experience today, in which I tried drinking water to wash the food down. The water didn't seem to help and I began to vomit. The sensation of something stuck in my esophagus is still there after vomiting for a couple of hours. I've tried drinking water and it comes right back up, making me feel as if I am choking. I can breathe for the most part but feels uncomfortable when I swallow saliva at times. I've tried searching the web and all I seem to find is that the vomiting has caused acids to come up which makes me feel something is stuck inside my esophegus. Any advise. Thank you much in advance.
