I believe many don’t know much about long covid so they try to diagnose and treat symptoms. Are you being treated for all of the symptoms you listed (are you taking anything to help you sleep, have you been given muscle relaxers, have you had a sleep study, have you had a brain or cervical spine mri to see what might be behind your headaches, have you seen a neurologist, etc.)? I would not delay getting diagnosed and treated because you can’t find someone to say it is all tied to long covid. I don’t think they have studied enough of the covid vaccines and viral infection that causes many to have long covid symptoms. They still need to know more about covid and the spike proteins impact on health. I have read there is significant impact to heart, lung, nervous system and endothelial cells.
