Tinnitus from Blowing Nose, Lasts About a Month, Reduced by Ibuprofen

[GoingGrayy]

I've got a 1400 Hz fluctuating tonal tinnitus that lasts about a month whenever I blow my nose too hard or let water hit my eardrum in the shower. Pressuring my ears changes it, and Ibuprofen reduces it. What might be the mechanisms at play here?
