Experiencing Dizzy & Loss Of Balance While Standing After A Popping Of Ear

Hi, two days ago I jumped from a platform (about 15 ft) into a pool of water during an obstacle course. I felt me ears pop under water. When I went to get out of the water and stand up I was very dizzing and unbalanced for a few minutes, then it went away. A couple hours later my ears hurt incredibly. I took ibuprofen and the pain subsided, but they felt clogged. Now one ear is sensitive to noise, still feels clogged and is ringing. There are no other symptoms and I have been taking sudofed pe to try to drain my ears. I currently started a new job and won t be insured for a month or so. Nor do I have the money to go into a clinic without insurance. Is there any advice you can give or symptoms I should track that would show serious injury? or is this something that often heals on its own and takes time?
