Hello everyone, I am a 25 year old recent college graduate from NY with a history of health anxiety. In 2013 I went to the neurologist with complaints of headaches and seeing double whenever I would look at text on a computer screen. She thought it was nothing but only ordered the MRI w & w/o contrast because I begged. Thankfully, it came back negative. I've had this whooshing sound in my right year as far as I can remember (maybe since I was 10 years old?). However, it was always a constant and subtle noise that sounded like wind by the ocean and never bothered me. Recently, that noise turned into the well known whooshing sound that matches by heartbeat. Sometimes its extremely loud especially if I bend over or did some strenuous activity and it goes away when I gently place my palm on my neck. I went to the ENT last October and she ordered me a CT, CTA, and CTV of my head, neck, and auditory canals. They all came back negative. I only found out they were negative because I had to go to the radiologist department myself after a week to pick up the results because she never bothered to call me back. I thought I was in the clear because the sound doesn't bother me; I just wanted to make sure it was nothing life threatening. Then my health anxiety kicked in and I started reading about the differences between MRIs and CT scans only to find that MRIs are much more accurate at finding things such as small tumors. I told my ENT that my main concern was finding a tumor and she assured me that they are very rare, my sole symptom of PT isn't convincing, and in the instance that one is found, it would 99.99% likely be benign. I've been skimming this discussion board, specifically this one on pulsatile tinnitus and it seems no one on here's cause is because of a tumor. I know I'm probably just overthinking it but I wanted to know how likely my PT could be due to a tumor if nothing showed up on the CT scan? Also my insurance preauthorized my MRI to be done in a facility where the machine is 1.5T and not 3.0T. Will that make much of a difference? Surely the doctor took this into consideration when the prescription was being filled out. Edit: I forgot to mention that the last 2-3 days have been extremely blissful, I can hear it but its extremely faint and only gets loud if I bend over.
