Ear ache

Brianna • TTC my Rainbow Baby ! Miscarriage 12/26/14 & Ectopic with Left tube removed 5/20/18😇😇
FML I wouldn't wish an ear ache on anyone .. I haven't gotten one in years .. What exactly causes them .. I've had this gross cough for about two weeks almost and a runny/stuffy nose I just feel like mucusy if that's even a word lol but seriously could this ear ache be from coughing so much?
