I can't find it in Google now. Maybe YCombinator doesn't keep older text post submissions? Sadly the internet wayback machine doesn't have any entries for HN from Jul 1, 2008 onward, so I can't find it there either.
Anyway their story was so similar to yours that it makes me think you are either that member, or have the same thing he had.
Here it is:

It is a long text post but it lists symptoms that are remarkably similar to the OP's.
Shooter said:
Basically I had multiple infections (both viral and bacterial) that were slowly eating me alive.
and
Anyway, I tested positive for at least a dozen viral and bacterial infections, but they could have potentially all come from one tick bite. I think the estimate is that 30% of all infected ticks carry at least one other co-infection. So, theoretically, I could have been bitten by just one really 'sick tick.' Or I could have picked up other infections once my immune system was compromised by an initial infection.
A few of the systems seem to remind me of my mother whom has recently been diagnosed with a pinched nerve in combination with known severe TMJ and migraines. (She apparently had a continuous migraine for about 15 years).
My main advice would be to seek out the experts, and try to find the ones who are able to admit what they don't know. UPenn is the first place that properly addressed my Mom's TMJ, and that in itself has made a huge difference. She's ended up helping them modify some of the textbooks.
Just as general advice, I'd highly focus on neurologists at first. You could also consider sleep centers, as the good ones do extensive tests and collect information that is harder to gather at any other location. I wish you luck.
HD could explain the fatigue, muscle tension, and reduced motor skills. However, it would likely also (but not always) be accompanied by other behavioral changes and cognitive changes.
You're also less likely due to age but i wouldn't rule it out on that basis from experience.
HD would not account for your numbness and dizziness.
Also curious if Wilson's Disease could be a more accurate fit. Fortunately, it's treatable.
