I Recently Ate A Large Bowl Of Popcorn That Had

I recently ate a large bowl of popcorn that had very "sharp" pieces on the kernel. About 5 hours later, I had horrible stomach pain, broke out in a sweat, and soon had diarrhea with many small blood clots. There can be no other reason than the popcorn. That was nearly 2 days ago, and my stomach is still painful and blood clots are still present. I tried eating a small amount of plain yogurt, but vomited it. What can be done, if anything. I'm thinking only time will heal it.......but how long should I expect?
