It can be very stressful and painful to be with someone you care about who is suffering. It sort of takes over. I might seek support from family or friends and try to get have your own special time for you. A counselor can also help.

And, if you and your husband choose to pursue the cause cause further, based on my experience and my research , some options include being evaluated by a Functional disorder specialist or be evaluated for post covid syndrome. There ate many ways the virus can attack the body. Did he have covid? It’s difficult to get a diagnosis, but if you can’t, treating the symptoms might be an option.

I hope you can find answers or treatment that helps. Take care.
