Fungal Infection?

I just got home from a doctor and was told I have a fungal infection in both ears. When they showed me what my ear wax looks like I was told “that’s how I knew you had a fungal infection” and I told her that’s how my earwax has looked for years.

I’ve always wondered why my ears smelled so bad and have always randomly had deep itches. I was prescribed ear drops for it but will the smell eventually go away? Does anyone know if hearing improves? I’ve never looked into this and never knew it even existed or I was struggling with it. Any tips to prevent this in future?
