@bunzman ... I don't know if my sinuses are causing all this or not. It sure sounded to me like my immunologist, who I have only met once for about 15 minutes via a telemed appt, seems to think my sinuses are the cause of most of my symptoms, though.

My brain MRIs all show "moderate mucosal thickening and regions of mucous retention cysts [that] involve the right sphenoid sinus." My MRIs also show "mild ethmoid sinus thickening".
