My ear won't pop back in and now everything is really loud and I'm having extremely sharp stabbing pain (26 year old female)

I had ear surgery when I was little and every now and then I would have to pop my ears but usually it goes right back to normal this time it didn't, everything Is loud I can hear everything going on inside of me I can hear my heart beat and everything around me. not just that but I have severe excruciating pain like a sharp stabbing pain every 5 seconds idk what to do will it be like this forever?
