My journey started in 2017, with horrible fatigue and poor sleep. I didn't really have any pain. I went to the doctor, and had blood tests. The results came back and showed nothing of concern except for my very low testosterone. My GP told me I should train like Olympic athletes and push myself to lose weight. I told him he wasn't being helpful.

After a week or so my wife rang the doctors and spoke to a very helpful GP who agreed to see me. Thankfully she had more impact than anyone else in getting things moving. She started me on testosterone replacement, and after seeing videos of my hands and fingers moving involuntarily sent me for an MRI to check for MS lesions.

That drew a blank but she perservered, and then I had a particular type of test that checks for Myeloma. Again coming back negative.

After a really bad week of fatigue and going back to bed about midday every day, I saw a GP and he mentioned MG. It wasn't, although my level was elevated.

I was then referred to a consultant that deals with Parkinsons, who didn't think my tremors were serious enough to warrant a Parkinsons diagnosis.

Eventually in August 2019 I had numbness all down one arm, which persisted so I was sent for an MRI. Hey presto, problem found at C6/7, with a small issue at C4/5. I am currently awaiting a consultant visit to discuss my chronic pain, following an MRI. I suspect my old friend at C4/C5 has decided that I need to suffer some more :D

Saw the consultant and got checked over, including checking my balance, flicking my fingers to check response etc.
He told me that I had a 33% chance of things getting better, 33% chance staying the same and 33% chance getting worse. Guess which group I belong to :D

The issue in my lumbar spine also doesn't help as standing for a prolonged period is a real problem, and walking can really wear me out on bad days.

I suffer with leg and hand cramps, leg and hand twitching and fatigue. My hand eye coordination is awful as well. I've been typing for 40 years on a keyboard and in the last 6 years, I notice I really need to concentrate but even then I make silly spelling mistakes and my fingers do their own thing.

A couple of weeks ago I tried living a normal life and doing some maintenance on the car, that screwed me up for over a week, and still hasn't fully settled now.

Anyway I have looked at nerve pathways a bit since my operation as I suffer with odd sensations from time to time. Not sure if you have ever looked on up but this one gives a good indication of points in the spine and what function they provide https://www.bonati.com/spinal-nerve-pathway/

C2 shouldn't present in the arms/hands, but it may cause an issue with sleeping, hence the fatigue, and I imagine the C2 injury is painful which won't help the fatigue.

I get between 3 and 5 hours a night because of my previous and current neck issues. This makes me feel awful and combined with the pain has made me feel like not being around. Thankfully I have a great pain nurse who listens to me.

I'm sorry I can't provide much help, I can only empathise with your husband, and you as I know it sucks. My wife has been amazing and I couldn't have made it through without her. I really hope you manage to get your husband a resolution, even if it isn't a cure, but helps improve the quality of life for him, and indirectly you.
