Edit: I want to preface this by saying that I'm not writing off modern medicine, nor post-modern medicine, nor saying that you should avoid doctors altogether. Just that it's a powerful and thus dangerous tool, and that you should ideally find a doctor you trust and then maintain contact with them, probably by visiting them regularly, now that I think about it, and maybe occasionally giving them a nice gift. :)

I advise the exact opposite, to visit doctors as little as possible, unless you experience pain which does not go away after a day or two.

In my experience, doctors will find something to do with you, and it will rarely work out to your advantage, unless it is emergency medicine.

My personal experiences: One doctor told me I need to get circumcised because I had minor irritation on my glans due to a scratch, which I told them about.

Another doctor insisted, without even looking at my X-rays, IIRC, that the cast on my broken hand was not sufficient, and that I needed him to take the cast off and perform surgery, or I would not be able to use my hand properly again.

If I had listened to these doctors instead of thinking for myself, I'd be without my precious foreskin and undergone unnecessary surgery, which would've delayed my getting better.
