[|Human|] I am occasionally throwing up blood with pain in my lower right side stomach area. I am under alot of stress and depression if that matters at all. I quit smoking for 2 years and recently started again to about a pack a day. Where before I quit I was around half a pack a day.
[|AI|]  Hi. Well, the first thing to decide ID whether the blood is coming from the lungs with cough or is coming from the stomach with vomiting. Secondly - if the blood is coming this has to be investigated urgently to see the cause, for example in your case this can be due to an ulcer in the stomach or the duodenum; or there can be blood vessel dilatation. Go for urgent Upper GI endoscopy and ultrasonography and an X-ray Chest. Proper diagnosis is a must to have a perfect treatment.
