any time you are vomiting blood it has the potential to be an emergency. if you have an ulcer bad enough to bleed that means stomach acid can be eating away at an unprotected stomach lining - which can lead to a hemorrhage. a good friend of mine nearly died that way. luckily he was taken to a hospital and pulled through.
can you have pain on both sides? i was told i have gallstones and peptic ulcers. also was vomiting blood.
