Ears Feel Plugged And Painful Even After Amoxicillin Course Completion

About a month ago, I was initially diagnosed with an outer ear infection. I was put on a 10 day rx for amoxacillin and antibiotic ear drops. After the ten days, my ear still felt plugged and painful so I went back to the er and they gave me a antibiotic shot, prescribed 10 more days of Cephalexin and gave me a stronger ear drop. When the 10 days came close to ending, I finally went to an ENT. He told me to discontinue the antibiotics and eardrops. He suctioned my ear out because he said there was a fungus growing. He discovered a hole in my eardrum and prescribed a powder to kill the fungus. Now (8 days later). I have no pain but my ear still feels plugged (sounds like im under water) and my ear drains a yellowish liquid. What can I do? Have a ruined my hearing? Im tired of the drainage.
