I’m not a medical expert, sqad and I bow to your expertise in such matters. However, in a case like mine where I clearly suffered tonsillitis a far greater number of times than the average, provided there were no reasons why I should not undergo surgery (which there were not in my case) then a tonsillectomy would seem to be a good way forward. This would seem especially open for consideration when my GP's prognosis that I would "grow out of it" was so patently incorrect. I also bear in mind that most children, when I was young, seemed to be whipped in to have their tonsils out almost as a routine as soon as they developed regular throat infections. Probably more than half of my friends had their tonsils removed (provided they were not registered with my GP, of course). Obviously anybody where surgery of itself presents a risk (e.g. those with heart or lung problems though I’m sure there are many reasons which suggest surgery should be especially avoided) should perhaps not be considered.
In my case the surgeon who lanced my tonsils told me quite frankly (and I’d no reason to disbelieve him) that I may not have survived more than another hour or two without his emergency intervention. I believe he saved my life but I also believe that my GP's rigid intransigence throughout my childhood eventually placed me in that jeopardy. He "did not believe" in childhood tonsillectomy. This belief may have had solid foundations when viewed against the almost factory-like facilities which seemed to exist then for children to have their tonsils removed (as I said, I saw three lots of kids come and go whilst having mine done). But I needed some long term remedy when it became obvious that I was not going to grow out of it and that remedy was denied.
Upon reflection I should have sought a second opinion - or at least my parents should. I would do if I was in that position today but those were different times.
