Pain after rupture ear drum has healed?

My 4 year old ruptured her ear drum 3 weeks ago. I took her to an ENT today and they said everything looks great. There is no more rupture and no infection, but my daughter still gets sharp pain in her ear. She is even waking up in the middle of the night in pain. Is this normal? The ENT didn't think twice about it, but I am concerned. Any thoughts??
