Hi, My Daughter Is 3 Years Old And Every Time

Hi, my daughter is 3 years old and every time she sneezes her ear hurts to the point that she Cry's, the pain only seems brief, 5 seconds or so. She has not had a cold in the last 3 - 6 months, we have taken her to our gp 2 weeks ago and she said the ear was a suspected burst ear drum from the past, and it was infected. She was given antibiotics.
Thanks
