Ear discharge when I using my AirPod (3rd generation)

Hi I have been using AirPod for more than 2 years now. Recently, I have noticed that when I using my AirPod some kind of discharge coming out from both ear and the discharge is coming for 2 to 3 days continuously. It’s really embarrassing when I go out. When I stoped using AirPod i feel completely fine and no more discharges. I was really love listen music with my AirPod than using other headphones but now I feel like a disappointment.
