Had treatment for external otitis, then my ear worsened started ringing 24/7. had a painful pop, felt fluid in my ear and it seams much better now.?

Ear Pop feels better: The pop was likely your ear canal opening up or may have been your eardrum moving rapidly. Try taking an oral decongestant for a few days, as this may help open your eustachian tube. Not getting better, go see your doctor.

Blockages opened.: Congrats! the pressure that was build up through the inflammatory processed has been released and and inflammatory fluid has washed out of your ear. Keep clean please.
