I am making no apologies for this! It’s really important and there is not a lot of evidence out there considering how disabling it is to many people.

Bulb syringing In most cases ear drops will clear a plug of earwax. However if this is unsuccessful a bulb syringe may be an alternative way to clear your ears from wax. An ear bulb syringe is a small bulb shaped rubber object which can be filled with water and then used to squirt the water gently into the ear to remove earwax. The main benefit of the bulb syringe is that you can use it yourself without needing to make an appointment with your practice nurse or GP. The risks of using a bulb syringe include ear infection, failure to remove the wax and eardrum perforation. These risks are low. Bulb syringes can be purchased from a pharmacy and can be reused. Please be aware that you should not share the syringe with other people for hygiene reasons.
