I guess, for a broken eardrum to heal.
I got an ear infection suddenly on Thursday afternoon. In a matter of 3 hours I went from feeling fine to being in extreme pain in my left ear. That night I barely slept it was so painful! So on Friday I went to the doctor for it, she prescribed me some antibiotics for it. Friday night I went to bed and once I got myself to ignore the pain and fall asleep I slept well all night. When I woke up in the morning I realized my eardrum had gotten a hole in it, most likely due to the pressure build up in it. Now I can't hear and it is still a bit painful, especially when I think about it.
Today I did a search and found that the dizziness is normal and will go away, but my ear may not heal for a long time and maybe not be back to normal again, meaning I might have permanent hearing loss from it. So NOT fun!
