Is it normal to have a nosebleed after taking a swab test?

I got one after I got swab tested. It went away, but around 4 days later, my nose started to bleed again. I'm afraid of what they're saying that it damages he blood-brain barrier. Is it true? I'm just scared because it might be a form of internal bleeding.

Swabbing the nose is bound to be at least a little irritating.  I wouldn't worry about it, though it's annoying.

If it was internal, it wouldn't be coming out your nose. The swab test is unpleasant but it's better than the prostate finger wave (unless you're into that kind of stuff).

Blood brain barrier ? No such thing. It irritated a vein in your nose. It will heal.
