yes these things definitely could be related and you should seek immediate medical attention by calling 911. the symptoms you describe could indicate an abdominal aortic aneurysm that requires immediate treatment. do not delay. i realize your question was posted 12 hours ago so perhaps you've already seen a medical professional. if the symptoms have subsided you still need to seek medical attention. best wishes to you.
i can feel a pulsating mass in my epigastric region and i have really bad lower back pain bothsides. are they related? . my heart is beating at around 120 and the pulsating mass is throbbing at the same pace and i've been vomiting.
