What could this be??

I'm wondering what this could be. Here are my symptoms: I've had pain when swallowing almost like my tonsils for a couple weeks now that Ive forgotten about. (I've tried to ignore it because my last time getting strep was extremely expensive), I have a headache on the back bottom of my head when swollowing, my ears have been popping (little painful) and sometimes I get a cough that makes me nervous because it almost feels like my chest is being sat on. I feel like I've normalized the symptoms for so long but it's only getting worse
