Nadia,
You may get some answers with a physical therapy consult. It is easy to have you lay on your back on the table, and a therapist feels with their hands to feel if your spineous processes are lined up. When one side of your neck is really tight, it can independently rotate cervical vertebrae and that happened to me which caused vertigo until my vertebrae were realigned again. It happened before I had my cervical fusion when I looked up, and now it doesn't, but I still get a bit of rotation and I recognize the early signs and can do some stretching to reset my neck. The vertebral artery runs inside both sides of the neck vertebrae, and when a spasm rotates the vertebrae, it stretches the artery. I you bend your neck, it kinks an already stretched artery and affects some of the blood flow to the brain. There other causes of vertigo, but this is my experience related to cervical spine issues.

If you are doing a lot of lifting in caring for your husband, that can pull on your neck and kick this up. You can apply to Mayo, but you probably need to be seen in person for a diagnosis. There are also hospitals affiliated with Mayo in the Mayo Clinic Care Network that have direct access to consult Mayo specialists and you get your treatment locally. Here is the map, and there are 2 locations in Ohio. https://www.mayoclinic.org/about-mayo-clinic/care-network/network-members

In answer to your question about my Mayo spine surgeon, he is Jeremy Fogelson at the Rochester campus. I had cervical central canal stenosis because of a ruptured C5/C6 disc that grew bone spurs and pressed into my spinal cord. He did decompression surgery with a fusion. If you do want to contact Mayo (any campus), you can use this link and they will call you back. If you want to use the Care Network, look for a specialist at one of the local hospitals and contact them directly.
