Wax should naturally migrate out of the ear, but sometimes it gets stuck in the bends and builds up, becoming impacted, dry and solid. It can also become irritating and itchy. Ear wax is hydroscopic/hygroscopic which means if it comes into contact with water it swells up, causing the ear to become blocked. People sometimes complain that they went for a swim, or took a bath, and then suddenly felt that their ears were blocked, and their hearing was reduced. Blocked ears often cause a ringing/buzzing sensation in the ears, or temporary tinnitus. Some clients report hearing their ‘heart beating in their ears’ – another typical symptom of blocked ears. In these instances, The Microsuction Company can definitely help you.
