Its to bad you couldnt get him in a sitz bath ! In my line of work I am often exposed to black mold and when I feel the symptoms coming on I drink a cup of hot cayenne and get in a tub with the water as hot as I can stand, then wrap myself in covers to keep it up ! I try to raise my body temp as much as possible and it works for me ,the next day all my symptoms are gone! In the past I have been layed up for weeks because of black mold infection!
