@jlaudon: Much thanks for pinetarsol recommendation. I'll look it up when I wake up tomorrow. Right now, it's all I can do to type this.
@Shooshie: Thank you so much for taking the time to read all of my site. I know it's a lot to read but I felt it was important that no detail be left out just in case it might have a bearing on my present predicament. So thank you again.
Your own story is horrible. Headaches like that are a living nightmare, so I'm glad you got yours sorted out.
I've emailed the Morgellons organisations in the UK to ask whether they keep a list of progressive and open-minded dermatologists and doctors. I'm still waiting to hear back.
And you're right about doctors. When I attended my first (and last) class reunion, I found that many of the guys who were great at book-learning but had no imagination or intuition whatever went on to become doctors. To them, status was everything.
I think I'll give the gasoline a miss though. I might be tempted to strike a match.

Thanks again for your kind thoughts.
@MIDI Life Crisis: Many thanks for the alcohol suggestion. Maybe rubbing alcohol might do something? I'll have to research it tomorrow. I'm dead on my feet here.
Incidentally, the Irish medical system is state-run. While there is private medical insurance available, most people here (including me) prefer to use the state system.
@kgdrum: Thanks for the tea and sympathy.

I get the odd not-so-bad day now and again. Today was hell. So all I can do is take it one day at a time. And hope.
Once again, gentlemen, thank you all so much for your support and kindness. I no longer feel quite so alone.
Kind regards to you all.
