Hi and thanks for the query,
Do not use syringe or any other method to remove wax. Its unsafe.
Please visit an ENT specialist
If you want to soften the wax you should put atleast 5 drops 5 times daily for a week.
Wax that is deep inside the canal will not come out no matter how many days you continue to put dewax. So it has to be removed by an ENT.
