I cannot tell if your ears are getting infected or not, but if they are....
When I was teaching/working in the Caribbean every summer I found myself plagued with ear infections. It truly sucked. These two things made all the difference for me.
1. An ENT made me quit cleaning my ears with swabs. In fact, he said he preaches against q-tips in the same manner a cardiologist preaches against cigarettes. To keep clean use a littkle soap on your index finger and be done with it. Some ear wax buildup is your friend.
2. I started using "Ear Beer" at the end of every dive day. Mix up a 1:1 solution of 70 % rubbing alcohol (easily found in Indonesia) and white vinegar. Lay down in bed, fill you ear canal, let it marinade for a minute or two and do not rinse afterward. Ear beer will not cure an infection but is great preventative
Since doing this I have not had an ear infection in ten plus years. I hope that helps.
