Hey I’m a 27yr old female. I’m happy I found this comment. I am too a hypochondriac. I have the same symptoms, the painless pulsing sensation on my left side by my temple. It caused me to go to the hospital in July 2025 because of the new feeling that I’ve never experienced before. It made me worry that there was something wrong like a stroke or brain aneurysm, because I’m a hypochondriac right?!?! & I also have hypertension. Well the hospital and doctors declared that my cat scans were normal and blood tests were normal. They did find a thickening on my left sinus. I have bad allergies and my nose is always stuffy or runny. So I thought that may be the issue…. Anyways fast forward to today as of January 4, 2026. I was at work and had to perform the heimlich maneuver on my client and stop him from choking. Which caused me to have really bad anxiety and made my heart beat incredibly fast. (Idk if this was the cause but the pulsation seems to happen when I’m under stress). This same painless pulsation came back and I went to the hospital panicking even more because this time it was so intense I couldn’t sleep & the pulse kept coming in 3 minute intervals. I went to the hospital and they ran cat scans again and blood tests but this time they put iodine in my IV and performed a iodine cat scan that would read if I had any abnormalities, inflammation or tumors on my brain. Everything came back CLEAR. So while they say we have nothing to worry about… in the back of our mind we are still worrying because this feeling isn’t a normal feeling. It’s January 6, 2026 & I’m feeling the same feeling but it was on set when I woke up to a loud bang. It was not intense like the one on January 4th…. So idk if these pulsations are triggered or what… I felt like maybe it is connected to the heart. Idk…. I really hope this helped you out. I know I didn’t give you an answer on to what’s going on but I wanted to let you know you are not alone! < 3
