Hi there
I haven't been on here in ages due to family obligations but stopped by today and saw your thread. I was obviously motivated to post. My signature tells my story.
So very sorry to hear you're dealing with these issues!
While I can't speak to IV abx, I can tell you that polyneuropathy (PNS) was my main issue with these infections.
It amped up on abx and then improved but it was still very much there there when I transitioned to herbals. After a good 22 months on herbals and tired of playing my own doctor, I moved to maintenance doses of a few herbs and hired a holistic NP to help fill in the many blanks I had after seemingly a gazillion hours of research.
Her first suggestion was methyl B12 shots and I got my first shot in her office. All I can say is holy smokes on how much it tamed my neuropathy (for a little while). Don't get me wrong, the neuropathy was still there but smoother/lighter/less dramatic (so very hard to describe) but this was the first time I experienced notable improvements.
My first Rx was for 3 shots/week (self-administered...very easy) and there was a major difference between the days I had the shot (significant improvements) and the days I didn't.
The NP moved me up to daily shots and I am beyond thrilled to report that the polyneuropathy is slowly abating.
There might be a quick second or two of facial or toe numbness on one day or maybe a light twitch...maybe some tingly toes for a bit. The more recent isolated stings seem to be gone. Full/partial face or left leg/toe numbness have been things of the past for awhile as are the buzzing/humming and/or buggy sensations I had. My urinary issues are finally gone.
The pathogens scavenge the myelin sheath that covers our nerves since it contains nutrients for them.
B12 is a vital component of nerve metabolism and Lyme patients with neuropathy clearly need more B12 than the average Lyme patient (who usually requires more than a healthy person)
I'm also taking omega-3 supplements since my testing showed my levels/ratio to be inadequate. Omega-3's are also a vital part of nerve health.
There are several other nerve-related nutrients for which deficiencies often exist in those with Lyme.
My NP ran an Organic Acids Test that was very helpful in identifying what I needed:
/www.greatplainslaboratory.com/organic-acids-test/Other companies offer the test as well.
Hopefully, you're following an anti-inflammatory diet because there are many things (dairy/gluten/sugar/pesticide residue, etc.) that can aggravate neuropathy in those sensitive to them.
Best wishes to you moving forward!
