I inhaled black mold. what do i do?

Depends on Exposure: Transient exposure to a small amount of mold is likely not significant. Symptoms usually only occur with very high levels of exposure like in an occupational setting. "Silo-unloader's disease" or "grain fever syndrome" has been described in workers exposed to large quantities of fungal material while cleaning silos but illness is typically self limited and workers recover without lung impairment.
