Weird Shock Sound in Left Ear

Hi there, I've had T since 2012 aproximately but wasn't bothered at all by it, after a sinus infection in 2014 it became more noticeable and went through hell, in 2015 I did TRT for 5 months and started to feel better, even forgot my T for days in a row (unthinkable when I was in my darkest hours). This year has been good so far but a few weeks ago I went through a lot of stress due to college and one day blamed a bad night of sleep to the T, since then I've been noticing it through the day again and overthinking about it, last week I heard a weird sound, like a high pitched shock every few seconds. Like a pulsatile T but doesn't follow the hearth rithm most times. I was wondering if someone experienced a similar thing.
Best wishes and silence for all TT.
