I am a 21-yr old female, no allergies, no medical conditions. I ate a different type of ham on Thanksgiving, just a few days ago, my throat was swollen for 6 hours. It finally went away, but I have had piercing abdominal pain anytime I eat or drink ANYTHING. This includes only water and toast. I constantly feel nauseous, though I have not thrown up. I still feel a constant piercing pain anytime I try to eat. Any advice?

Go to a doctor. Any pain which does not go away quickly or marked change in eating is a big signal to go to a doctor.

Any sort of severe pain should be taken seriously and investigated and treated.
