POOR BABY, both you and her.
I know this might seem hokey, but see a chiropractor.
It helped me, my brother & sister.
not to mention my husband and our child.
I had swimmers ear my whole life. They wanted to put tubes in my ears.
Then a family-friend suggested a chiropractor. My life was saved (I'm a little fish to water) and showers, pools and swimming in the ocean were no longer off limits.
When my little-man, myself and hubby all got an ear infection, instead of going for the meds, I went to my chiropractor. and low and behold our ears began to drain on their own!
You can write it off as coincidence if it were just one person, but this was for myself (for the second time), my husband and our son ( who was barely a year old at the time).
Not to mention my siblings when we were younger (ages 3- 8).
