They do exist. As an ex-sufferer, I can vouch for that. Couldn't putt for two years and I will admit that a poor technique was the start of it. In my case, I couldn't take the club away when I wanted. When I did, it was involuntary, snatched and unpredictable. It didn't matter if it was 2ft or 20ft, the same condition. Nerves never really came into it.
I cured it by moved to a Odyssey two-ball, hovering the putter and quickening up the putting process.
Sorry Sir and no disrespect to you at all but that all seems placebo to me. A change of putter and technique "cured " you. That to me says it was a
technical fault rather than a "condition" that you had. I'm going to be a non-believer until i experience this myself.
