With the technologies available today this kind of thing is something I would have expected neurologists to be all over by 2017, but I'm not going to start on that topic...
My suggestions are:
Environmental
Minimise your exposure to electric fields and electromagnetic fields and radiation. If like most of us your home is dotted with AC outlets, avoid spending too much time right next to outlets or the wiring within the walls. Don't use wifi or wireless devices that transmit constantly (traditional remote controls and infrequent transmitters like wireless doorbells are fine). Don't carry your cellphone on your person when not absolutely necessary.
Experiment with electrically earthing (grounding) yourself, especially while resting. This can include going barefoot outside, buying off-the-shelf earthing products, or making your own earthing products if you have the skills and basic electrical knowledge. There have been discussions of earthing on this site.
I find that keeping my body cool is critical with these kinds of symptoms. Given that you don't identify as living in a cool part of the world wearing a cooling vest might help if the same applies to you.
Herbs
Cannabis seems to be the go-to herb for systemic neurological issues, except for the possible legal consequences of going there. It's more effective (and efficient with respect to quantity required) ingested rather than inhaled.
Practitioners
While the field of neurology remains asleep at the wheel the only practitioners able to recognise that your nervous system is in difficulty will be those with highly-developed palpation skills (i.e. those who can feel it with their hands). Included in this group are practitioners of manual medicine (e.g. osteopaths, chiropractors) and Japanese styles of acupuncture (e.g. Toyohari, for historical reasons I won't bore you with here). How much they'll be able to help you is another matter, but they'll agree that something's wrong and perhaps even be able to put a label on it (e.g. Traditional Chinese Medicine has a diagnosis of "internal wind").
The top of the tree when it comes to palpation skills, effective intervention, and labels that are derived from Western science and medicine is
cranial osteopathy. Cranial osteopaths recognise and can treat numerous phenomena that may or may not be in play for you but could definitely drive your symptoms, such as nerve facilitation and what they call the Primary Respiratory Mechanism. In your country they are generally also medical doctors.
Other Interventions
A thermograph could well show abnormalities. Whether a doctor would know what to do with it is another matter, although it might help to convince your husband.
If there are specific sites of neurological craziness then
quadrapolar magnets can help dampen it. The trick is figuring out where to locate the magnets (and by extension, exactly which magnets you need). If you have joints in your spine that are especially stiff or spongy when prodded they'd be good places to start.
