I had exactly what you speak of in your post. I also had tingling of half of my head (scary I know!). I had tingling and even numbing of the left side of my body, both extremities. I was given a very high dose of B vitamins that supposedly helps with this. Didn’t do a thing.
I don’t have this in months as I am 99% symptom free, but I do believe that physical therapy I got in September and maintaining those exercises helped. I remember that before my treatment I had these symptoms and those got much worse during the first 2/3 of my treatment. I think that candida and treating it overload our bodies and everything you have wrong escalates then: back pain, weak nerves…
Try to do some simple exercises for the posture, your neck etc. If you can get them through your GP that would be better since you would get professional advice on what works best for your symptoms. Yes, doctors are not completely useless… in few areas 🙂
Best of luck to you!
