Does this sound like pulsatile Tinnitus?

I’m 26, female. Sometimes when I stand up, I’ll get a whoosh in my left ear. It’s like “Shhhhhhhhh” sounding. It also happens when I bend over/stand up. Or when I stretch my arms in the air. It only lasts for maybe 10 seconds. If I press on my neck under my ear it stops. But either way it stops after like 10ish seconds. I have health anxiety, so I’m spiraling a bit.
