The only time my son who had tubes was prescribed ear drops was when he got an ear infection while he had the tubes in. My son got ear infections when he got water in his ears. I had ear plugs custom made for my son because the mouldable wax plugs always fell out when swimming, even with the neoprene headband. Is he only in pain when you put the drops in, or all the time? If it is just when you are using the drops ask the doctor, or another doctor if you need to keep using the drops.
