It's been a week since I got a cold. During this cold I've experienced some painful ear popping and fullness when I blow my nose. but I'm pretty sure it was my congestion causing this symptom. Since it's been a week now my ear has been ringing mainly noticable at night. Conversations or semi loud noises I can feel the sound waves in my ear like bass. I usually watch videos with earbuds and there aren't any problems it's when its night time I notice that videos with my ear buds sound robotic in my left ear. I don't have any pain nor the feeling of fullness. I do have some balancing issues when I put pressure to my head (like lifting something heavy and the blood goes up). I do feel I tiny bit of congestion but barely noticable when going through my day. Is this causes by the cold or?
