My experience has been reasonably good.
There is, however, a however.
When I was a teenager, I started getting gunge pouring out of my right ear. I went to the doctor and was told I had catarrh. The discharge got worse. One morning, my pillow was covered in blood. I headed to A & E pronto.
To cut to the chase, I ended up having seven operations resulting in a huge mastoid cavity, and I'm about 60% deaf in that ear. The surgeon told me that if it had been left, I could have got meningitis and died.
When I taxed the GP about this, his response was "you had catarrh to begin with."
Yeah, right!
