An ear that won't pop can be quite uncomfortable! This often happens due to pressure differences, like during a flight or cold. Yawning, swallowing, or gently blowing your nose with pinched nostrils sometimes helps. Have you experienced this for long, or is it a recent occurrence? It's important to pay attention to any pain or hearing changes, so visiting a doctor might also be a good idea. What's your primary concern or curiosity about it?
