While lying on your side, fill the ear canal with olive oil drops, allowing 5 minutes for the oil to soak into your ear canal to help soften the wax. A plug of cotton wool will help keep the oil in the ear. Fill the canal slowly (to avoid airlocks and flooding of oil out of the ear canal).
You can repeat this for up to 2-3 days before your appointment (at least once before your appointment is beneficial).
It is important that you DO NOT use drops if you have a hole in your eardrum/an infection/grommets. (Please avoid using Waxsol ear drops).
