My 78yo mother a couple of weeks ago was sitting on her porch drinking coke and chewing the ice when she suddenly started spitting up blood. She would simply clear her through and there would be a rather large amount of blood. It is bright red but not frothy. We took her to the ER where they did an EKG, chest x-ray, bloodwork, etc. Nothing showed up. Her o2 was in the upper 90's which seemed good for a 60+ year smoker. After about 1.5 hrs, it stopped. The ER discharged her after talking to her new pulmonologist (her old one retired). She went to her a couple of days later and she ordered a CT scan. We are still waiting on the results. She hasn't had bleeding to the extent of that night but occasionally, it will start again for a few minutes then stop. It seems to happen sometimes after eating but not always. But she seems to have no other symptoms.
She is in relatively good shape for a 78yo smoker. She has pulmonary nodules that have been being followed every 6months with little change over the last 7 years. She is on BP medications and her BP has been averaging around 150/90 for several months. She had a fem pop bypass in January (from the aorta) which went well other than a considerable amount of blood from the NG tube.
My question is where could this be coming from? I would think if it was coming from her lungs she would really have to cough to bring it up. She said it feels like she can feel it right in the back of her throat about where the Adam's apple is.
