Yes, sometimes our ears can get blocked by earwax, which can make it hard to hear. Earwax is like our ears' way of keeping them clean, but sometimes it builds up and gets stuck. When this happens, it can stop sounds from going through our ear canal to the eardrum, causing temporary hearing trouble. The good news is that this is usually easy to fix. A doctor can gently remove the earwax, and then our hearing should go back to normal. So, if you ever feel like your hearing is muffled, it might just be earwax, and it's a common and fixable issue.
