My daughter had an operation 7 years ago i thnk it was a myringoplasty , she is now 15 and has been suffering with tinnitus, vertigo, and sickness and falling down for 3 weeks, Gp referred her to ENT and awaiting an appt, but i took her back today as she is in loads of pain and they have made her an emergency appt for tomorrow at ENT dept as they say they think they can see a perforation again and also white stuff all over the ear drum- she also has pain when touching behind the ear, the gp is querying a choleastoma- what is this and should i be worried or what else could it be
