If u have never had this issue before then this looks like an acute infection ... Which can be treated by meds .. will need to change the meds if u r not getting better .. may require culture of pus

If this pus Has started in a few days only and never came before so it’s an acute infection it will respond to medicines but you need to change your medicines you are taking. So we need to know the previous medicines you are taking and we need to know the nature of pus the colour and consistency and details about hearing aspect as well.
