I have entered my first Triathlon which is on 2nd April. I have been training twice a week in a pool for the last two months with no problems. Last Sunday I decided to see if I could still do tumble turns and tried it in the deep end. I regretted it instantly as I had a sharp pain in my right ear. I have a perforated eardrum caused by a T Tube falling out which was inserted about 20 years ago. Needless to say, I am now on antibiotics for an ear infection. I would like advice on what ear plugs/hat to get to enable me to carry on training/competing. Does anyone else swim with a perforated ear drum?
