@sb4 I read lotsa studies a few months ago before deciding how to proceed and the studies where they used MRI whist applying auricular t-vns suggested in my case the upper concha might be good for a trial. Another effective place seems to be the inner tragus. The vagus nerve does innervate a large part of the ear but the same neuro-modulatory effect does not apply to all points.
https://www.ncbi.nlm.nih.gov/pubmed/27898202 there are copies of the whole study available online I think, and much more if you search for t-vns or at-vns.
Slow motility - yes definitely, I saw improvement there immediately even with non electrical vagal nerve stim, which I started with first actually.
The most striking improvement is in resiliency in response to movement up and down (getting up quickly from a low chair or the ground) and in the car if we're travelling fast or around corners. My vertigo has improved, and stamina over the course of a day has too. While I am actually using the TENS (I wear it shopping, travelling in the car, to kids music lessons etc) I feel something I can best describe as micro adjustments in the ANS...to movement, to being called upon to answer a question...
I have had a couple of instances in which I have actually felt recovered - once for just a few minutes and once for a few hours. I need to crack the code on what's going on to give me that much improvement. I have a strong feeling it may be gut bacteria related and I'm hoping to try Rifaximin soon to see if I can make further headway.
I feel much more resilient in general! I've always needed to pace my exposure to too much of the news, busy noisy places, confrontational people (just as a few examples) and I seem to have a much higher tolerance for those kind of stressors...or ex stressors lol. Might be worth noting I had sensitivities in those areas prior to developing ME.
There's also clearly some anti inflammatory effect in my case. Did you ever do cold induced thermogenesis? Very much like that...without the cold.
I'm assuming a significant factor in how well I respond to CiT may be vagal ==> anti inflammatory pathway related?
Hope that's helpful.. Reading back I'm thinking t-vns hasn't exactly helped me with an ability to be succinct. ...Maybe that's just around the corner...haha.
