I never fly without my EarPlanes!! I use them as well as a sinus pill (OTC cold type) and nasal spray (again OTC cold type). I still can have some issues but NO PAIN!! Unless the descent (which I find worse than takeoff) is really quick, I am fine - no muffled ears. I try to make sure to swallow a lot (chewing gum helps with this) on the way up and the way down. I can hear my ears popping when I do that. Yawning also works great to pop my ears!
Make sure when you put the EarPlanes in that you don't push them in too far. I usually reach over my head to pull up on my ear and then twist the EarPlane in until it doesn't want to go in any further without an increase in force. (Hopefully that makes sense!)
