I have had many of the symptoms you mention: tingling/prickly feelings in the extremities, numbness sometimes halfway up my calves, blurred vision; sometimes my arm shoots straight up in the air in the middle of the night. I also had horrible restless legs and restless SPINE!! when pregnant, and a few times afterwards. This is not to mention the brain fog...
A few central thoughts:
I also had an earlier bout of odd symptoms in 2004 (before I was diagnosed with active Lyme in 2008)....sudden dimming/loss of vision and hearing(but I'd be completely conscious, it was like being trapped in my head and can't communicate with world for a few seconds), neuropathy, various cognitive problems including getting lost....after many docs practically laughing at me and my own research, I did find it was B12 deficiency, even though blood and spinal levels were "normal".....***BUT BUT BUT**** there ARE DIFFERENT FORMS OF B12. The typical one is cyanocobalamin.....this did not TOUCH my symptoms. Make sure you are taking the METHYLCOBALAMIN form of B12, from which your body can readily use the methyl group. 2mg daily orally of THIS DID THE TRICK--symptoms left within a week. When I recently had some restless legs symptoms, I asked my LLMD to prescribe me shots of methylcobalamin B12. You will not find these at your doc's office...you have to find a "compound pharmacy" which mixes up specialized concoctions. I found a compound pharmacy, and the methylB12 shots cleared the restless legs and improved all my neurological conditions a bit.
MY THOUGHT OF THE CIDP:
I am not a doctor, so please take that into account! But my take on Lyme: since I have had Lyme I've had anxiety, depression, tachycardia, high bloood pressure, hypothyroid, muscle pain, neuropathy, brain fog, memory problems, weakness, temperature, etc.....in other words this one disease triggered 35++ other conditions. So you may fit the diagnosis, but personally I would go after the Lyme, and try the methylB12......I have been treating myself with Cowden herbal extract formulae for 2 years. Some of these conditions are receding.....INCLUDING THE NEUROLOGICAL ONES. I think most Lyme-caused diseases are caused by the Lyme toxin, and are made even worse when we herx while treating the Lyme...but once the Lyme begins to clear, these other conditions--even the seeemingly permanent conditions...for me they seem to be clearing. I hav e only mild neuropathy, I still have brain fog, high blood pressure...but many other symptoms cleared. The restless spine syndrome (there is no such known condition, my doc of course thought I was a nut--but it's restless legs in your spine....can't bettter describe it).
So, try not to be too anxious....Lyme is evil, it wreaks havoc. Some effects/Lyme caused conditions can be permanent, but our bodies, including neuronal networks, are remarkably resilient, I truly now am a believer most of my symptoms will clear. My memory will never be the same, I will always have slightly numb cold fingertips....but the other scary scary things are gone.
I hope this helps...and remember, my comments are a layperson with Lyme, not a doctor....
