I Was Doing Burpees (an Excerise Where You Basically Go

I was doing burpees (an excerise where you basically go to the ground and get back up) two days ago when I felt a pop behind my left ear, inside the skull, slight pain. I stopped, walked it off for a little then tried one more to see if it hurt again and it didn't. I wrote it off as nothing but today I got home from work and laid down for a second and out of nowhere the same slight pain happened in the same spot just no pop. A mild to moderate headache insued on the left side of my head near the temple and a little light headed but gradually feeling better. Is this something I should be going to the ER for?
