My friend got slapped in the ear from what she told me it was a hard slap. After the slap there was a ringing sound in her ear and then it went away. Now she can't hear well from her left ear. It's as if her left ear is clogged. There is no pain from the ear at all. We are very worry because she has no medical. Done numerous of research and we think it might be a rupture eardrum but no drainage. Is there anyway she can heal fast other than seeing a doctor?
