a tiny amount of blood would not be a cause for alarm. the skin lining of the ear canal is rich in blood supply so you most likely irritated it when you used the q-tip. it is best to never use q-tips inside the ear canal. one of reasons water had a difficult time coming out of ears is because you do not have a adequate protective coating of (ear) wax. when water meets a waxy surface it will just bead up and fall out by gravity but if you do not have a waxy surface the water will remain.
i had water in my ear. i put a q-tip in to absorb it. not far in but it had a tiny bit of red blood on it when removed. . my right ear has always given me a problem because i use a syringe to clean out my ear when i was a teenager and it hurt all day long. now it always is very sensitive and hurts when you put anything in it. do i need to see a doctor about this ear?
