What Causes Persistent Ear Pain Despite Taking Paracetamol And Cymbalta?

15 days ago while descending on a flight I started crying pain in my ear was so severe. Since then it s hurt a little and feels like fluid in it. I ve also heard sounds and voices are muffled. I put it down to my manieres disease however pain today is getting back to almost as bad as when it happened. What could it be or is their something at home which may ease it? I suffer from CRPS and have a 12 mcg fentanyl patch take 2 end one 4 times a day the same of paracetamol 120mg day of cymbalta 150mg at night of serequel to sleep, cannabis oil and it s still hurting so much I can t sleep. It s hard to get out anywhere so Dr isn t an easy trip. Thanks, Lisa
