Ear wax results from a process of the normal body immune system. This is in place to ward off bacteria and accumulation of dirt in the ear tracts. The ear wax can sometimes find its way to the outlying areas of the ear tract. When spotted, washing it off becomes easy.
If left unhindered, the buildup of earwax leads to blockage in the ear canal. This can affect either ear or both. This may even cause hearing problems. It is commonly reported that usage of cotton swabs can lead to blockages by pushing the earwax into the inner tracts. This is where care needs to apply when cleaning the ear.
