Does this sound like Long Covid?

For about five years now, my husband has had crushing fatigue, where he’ll wake up refreshed, but then he’ll need a nap an hour or two later and then take a second nap in the afternoon, and still sleep 11 to 12 hours at night. He doesn’t seem to have post exertional malaise. He also had chest pain and shortness of breath. Those last two eventually went away, but were replaced by dizziness and brain fog about two or three years ago. Then about a year ago he developed a slight hand tremor. His PCP referred him to a movement disorders neurologist. The skin biopsy test for Parkinson’s was negative and his hand tremor is not like the usual Parkinson’s tremor. The neurologist never mentioned Long Covid but that’s what I’m starting to think this is.
