Wax forms naturally in the ears and usually runs out of the ear naturally also. Sometimes for various reasons ears can become blocked with wax. If ear softening drops do not remove the wax, you may need ear irrigation (formerly called syringing) by our Practice Nurse to dislodge it. NEVER USE COTTON BUDS TO CLEAN YOUR EARS – this often makes the blockage worse and may cause an infection “otitis externa” which can become recurrent.
