Funny thing about
Lyme arthritis - I've had my blood checked a few times and there have never been any arthritis markers in it - but that was years ago - around 2005. I have developed osteoarthritis since then, so no point in checking now.
When I was infected with Lyme this last time, I noticed that on days where the barometric pressure was considerable low (29.97 & below) I had a ton of severe bone & joint pain, and I was a pretty good indicator of when a 'bad storm' was coming in to our area (LOL!). Now, the barometric pressure doesn't bother me hardly at all, and although I can sure tell when a storm with a lot of moisture in coming in, it's not the same. The pain isn't as intense/sharp and it's relieved much, much easier now.
After I healed the first time around, I had no signs of arthritis at all, so no, I don't believe that Lyme arthritis actually sticks around either, although I only have my own case to go by. I've not found any studies that have been done on it yet.
Nerves take time to heal. Just because the bacteria is no longer attacking it, is doesn't heal spontaneously. Nerves can take up to 7 years to heal. When I had been healed for 2 years, I had no tingling at all, no muscle twitching, only a few very small numb patches on my skin and things like that. Maybe if I had had more time as a healed person, I would have gotten rid of the few numb patches too! I plan on finding out this time.
Lyme attacks the myelin sheath - the protective covering on the nerve, and if it's left to continue on, it will eventually attack the nerve itself. It just takes time for that kind of damage to repair itself, it's not that it can't. There is always a chance with a case like mine where the person has had it for many decades that the nerves can be damaged to the "point of no return" - but no one knows until they have given themselves a full 7 years of health.
