I just took a gander at the symptoms of Lyme disease, and, well, since Lyme disease can cause death by way of meningitis-- though, it's not said to always do that-- I don't particularly remember people with Morgellons having anything like a fever. Fatigue, yeah, but... not a fever, or a lot of the other Lyme disease symptoms.
As for a cure-- well... let's see what I can dig up.
From what little information an Internet search has provided me, it seems that a cure for Morgellons, or, at the very least, a treatment, may be related to the cure or treatment for jock itch.
It is also noted that Morgellons, while thought to be a disease, may or may not be due to a person's acute sensitivity to different chemicals. While it may be a disease, still, it would be a good idea to vary your diet, and see if your symptoms stop once you quit eating or imbibing something you usually do.
A short aside: It appears that Morgellons is getting grouped together with diseases like jock itch and ringworm. Perhaps there's a treatment for those that would help for Morgellons?
This is particularly off-topic, but, while I'm at it, I would just like to state my opinion that Morgellons, whatever it may be, it's definitely real. I posted an entry about it on my blog, and somebody came up to me out of the blue and said that their father had it.
Whatever it is, it exists. And I definitely think that it's related to exposure to insecticides or pesticides, as that seems to be where a majority of people who experience the same symptoms of Morgellons are coming from.
So, if anything, it would be a very good idea to wash your fruits and vegetables off that you get from the store before eating them, and, better yet, also wear gloves when touching things that have pesticides or insectides on them.
Oh, and finally: It has to exist, as a great deal of people urge others that they have it when they're finally told that their experience is not unique. There's quite a bit of an "Ah-ha!" when people find out that they're not alone in experiencing the symptoms.
