Earwax buildup occurs when the body produces too much cerumen, the natural wax that protects the ear canal. This can lead to a blockage, causing discomfort, hearing loss, or even infection. Factors such as using cotton swabs or wearing hearing aids can contribute to the problem by pushing wax deeper into the ear. Symptoms of earwax buildup may include a feeling of fullness in the ear, ringing in the ears, or difficulty hearing. It's important to avoid trying to remove the wax yourself, as this can worsen the situation. Consulting a healthcare professional is recommended for safe removal.
