Definitely researching this now.
Seems that this virus is responsible for peptic ulcer, but only effects about 1/3 of the people that have it.
Too much pain-killers.
Nonprescription NSAIDs include aspirin, ibuprofen (Advil, Motrin, others), naproxen (Aleve) and ketoprofen (Orudis KT).
I guess acetamanophin (tylenol) isn't included here.
