The wax shields your canal from moisture, infection, damage, and other objects. However, issues might arise from an accumulation of wax. Congestion of the ear canal is known as impacted earwax. Anyone is susceptible to developing impacted earwax. An estimated 10% of children and 5% of otherwise healthy adults have it. People relying on hearing aids, earplugs, or earbuds are more prone to experience this. Impacted earwax can be diagnosed with a thorough medical history and examination by your doctor.
