What Causes Perforated Eardrum And Temporary Deafness?

I grew up in severely abusive family and for awhile when I was 6 I went completely deaf for months and had to go to hosptal cos apparent;y it was due to wax build up (according to abuse parents) and was deaf for moths and then spent quite awhile in hospital..but every doc who checks my ears,just for random checkups,has said one of ,y ear drums is perferated and apparentl this kimd of injury is from being punched in the ear cos of the details...the doc said she s only seen that injury from ppl being punched,something to do with the injury and the way it was done...and always told went deaf as a kid cos of wax buildup but sometings just dont add up...where would I go to get this checked out properly (and freely) and it does mean alot to me cos I just know something dodgy is going on and its the only thing my divorced parents agree on and always have but along with perpetrated eardrum...and months and months of being deaf and then considerable time spent im hospital...something just doesnt add up and although not much about childhood adds up..the most bizarre thing is that my parents...who have been divorced since I was a baby...and cant even agree on year they got defenced or if my conception was mutual or rape...but they ve always been staunch on this going deaf thing and it just doesnt feel right and doc said she s only seen this injury from being punched in the ear but docs just say... oh you know whats going on with your ear??but I dont and they never explain to me properly...
