@supporthusband I had electric shocks down my entire body if I bent my neck. That is Lhermitte's sign. The reason that was happening to me was because of spinal cord compression from a collapsed disc and bone spurs that were pushing into my spinal cord. I had spine surgery that fixed this and decompressed the spinal cord. If your wife has not ruled out a possible spine problem, it may be worth it for her to see a neurologist or spine specialist. This kind of problem can sneak up on you from an older injury and may not be causing pain, but can cause permanent damage and can put a person at risk of paralysis. Problems like this are best addressed before permanent damage happens.

Shocks are usually nerve pain from compression somewhere. A neurologist can do testing to figure out where that may be happening. It could be in the body in peripheral nerves or in the spine and could create similar symptoms. I'm glad your wife has found something that helps her sleep, although it sounds like no one has figured out the source of the problem. Would she consider an appointment with a neurologist?

I'm glad she has found relief because I relate to her misery. My issues were completely tied to my diet- processed sugar which elevated the yeast in my body. I never had any testing as to this issue, but because I have eczema many suggest dietary changes. The yeast which live in our intestines, discharge waste though "leaky gut" issues that come with age. I had several complete neurological work ups, nothing was found. I never had external yeast issues. It took about 6 weeks giving up all sugar, processed and natural to realize this diet was making a difference. After 2 months the sensations stopped. Now 4 years later and no processed sugar and limited natural sugar I have zero issues, so no need for me to try the GABA. If the GABA stops helping her , she should consider a sugar detox to starve out the yeast. Also read The Yeast Connection Handbook by William Crooke, Md. Yeast is tied to many autoimmune diseases.
