Had a bad ear infection that last few days, where my hearing was muffled and I couldnt hear, now if I pull my ear out it pops and I can hear. Normal?

Blocked ears. yes can happen, your external ears can become blocked with wax/debris after infection, when you pull your ears out it pops and you can hear when the blockage becomes partially open, your doctor can perform ear wash or prescribe some ear drops to dissolve the impacted wax.
