i don't know. i do not know anything about your wife her habits her medical history nor do i have a way of determining the source of the blood based solely on your posting. she would need to see a medical provider and be properly examined if this continues. hemoptysis (blood in the spit) can have numerous causes from simple bleeding for irritated or infected throat or nasal tissue to more ominous causes
why is there blood in my spit when i clear my throat. my wife woke up this morning and when she cleared her throat and spit it out there was blood in it. she has been feeling kinda crummy lately and her throat has been feeling kinda scratchy. what could this be?
