I'm getting over a bad cold and has been blowing her nose constantly. My left ear feels funny, like a clogged ear. They need to pop but won't. I thought maybe a decongestant would help, or opening her mouth as wide as she can--that helps me sometimes when my ears won't pop on a plane. I tried opening her mouth and even moving my jaw back and forth but it didn't do anything. Any help would be greatly appreciated!
