Weird hollow sound in left ear?

My inner ear was really itchy and i decided to use an ear pick to try to get the ear wax out. I did that and than i eventually used to a q-tip and shortly afterwards every time i bite bringing my teeth together theres this weird hollow sound like someone hitting a jug of water or something. It doesn't hurt its just a hella annoying. Its lasted for a day now and its really annoyingg. I am wondering if this could be an ear infection or will this just go away by itself! thanks guys!!
