Hallo. I Am A 43 Year Old Female With No

Hallo. I am a 43 year old female with no significant past medical or surgical history, I weigh approx 140 at 68 inches, and I have been relatively athletic for most of my life, including now. I take no medications and have no known drug allergies; my blood pressure generally ranges between 100-110/60-70 depending on whether I am adequately hydrated and my annual labs have always been within normal range across the board. For the past six months I have noticed that when I bend down (or if a child screams loudly near my right ear) that the sound in that ear is both amplified and distorted with a buzzing timbral quality to it. This is not accompanied by any other symptoms and immediately resolves once I am upright. Any thoughts?
