Hear myself breathing threw ear at times. Like it pops and feel air in ear. Ears crack when I swallow too.

Middle ear effusion. Or eustachian tube blockage or congestion can cause these types of symptoms. Things such as allergies or OM can cause these symptoms. Occasional cracking in your ears when you swallow is not necessarily the sign of a problem either. If persistent and bothersome or additional symptoms develop, then seek an exam.
Serous otitis media. You have a serous otitis media and/or blocked eustachian tube. You need a good ear exam to remove a wax impaction if one is present. Otherwise, it generally is a matter of time until you get better. Best of luck.
