Hello Doctor, I just got back from urgent care. I couldn t get my nose to stop bleeding (2 hours of non-stop bleeding). The doctor at urgent care packed my left nostril (where the bleeding occurs), and referred me to the ENT. From my observations, from the multiple nose bleeds, I believe I popped a blood vessel. My question is, can someone pop a blood vessel performing oral sex? I tend to hold my breath , and get tear-eyed when coming up for air. This question is a bit uncofortable to ask, but am concerned. Thank you.
