Yea I was going to say either wisdom teeth or ear ache. Ive always had problems with my ears, I got tubes put in to help with drainage when I was about twelve, and thought it was all corrected. About a year ago, my ears started acting up again, lots of ear aches, and my ears cannot drain, water will stay in there but will not come out causing ear infections repetitively. So I went to my doctor after a few months, and he sent a referral to my specialist, An audiologist, and Here I am 6 months later, Still waiting to meet her to see whats wrong with my ears, Ive called numerous times and get the same answer like it takes time, apparently thats healthcare for yea in canada. Moral of the story, Don't let it get worse, go see a doctor, because chances are you will be waiting a while.
P.s, does it feel like there is any pressure inside your head? like in your ears? and can you pop your ears?
