hi Jessecured, I know this post is almost 2 years old but I am having this same itching issue. I believe you are correct it is overactive nerves(itching is all over). I thought it might be liver related but may or may not be(Labs look perfect however did have fatty liver diagnosis over the last two years). According to blood work I am also not diabetic. I notice the symptoms are much more intense when I am on a low carb diet trying to lose weight(I am approximately 30 lbs over weight). Maybe ketosis is making my body more acidic. Caffeine also exaggerates the itching so I stay away from it. Did the vitamin C and omega 3's treat it or did you have to continue this as on going? Right now I started vitamin c and started taking alkaline mineral salts. I also take a tablespoon of olive oil with turmeric and pepper in the morning. I have done serveral parasite cleanses(2) and liver flushes(18) and still have this problem. Any help would be greatly appreciated.
