It's not exactly normal for this to happen, but it's not unheard of either. Your nose and tear ducts are connected so during a nose bleed if you lean your head back some of the blood can go back upwards and come out of your tear ducts. It's also possible to breathe through your tear ducts, and you may notice when you cry your nose runs in part because of tears leaking down to the nose.
no
normal
I just gave myself an electric shock while TIG welding, and got a nosebleed, so it would appear the answer is yes.
Yes
For a while after having them yes, but will return to normal.
It depends on what type of discharge. If the discharge is blood, then of course it is normal.
Its normal,its just the blood inside flowing.
do what normal people do in this situation: go to the toilet.
No.
Yes it's normal, you have a tiny tube that runs from your ears to the back of your throat, this can get blocked with flem and cause the sensation you describe.
A normal, or ideal blood pressure, would be 80/120. While some individuals may vary from a high-normal of 85/130 to a low-normal of 60/90. Each individual is different.
The best way to treat a nosebleed is by holding the head forward to avoid blood going down the throat and stuffing tissue in the draining nostril. One can also pinch the nostril close while breathing through ones mouth. Holding it pinched for at least five to fifteen minutes helps. Some people have suggested applying ice to bridge of the nose or forehead to constrict the blood vessels.
