Is blood clots during a nosebleed normal?

Hi there my question dont concern me but my younger Brother out of no where he calls my name and asked me to "look at this ,is this bad when this happens "and as I look in the toilet there's a big blood clot in there (I mean big ) and as I questioned him he said " it felt like something in my nose and when i blew it it started to bleed and this came out" im stumped here and I need some advice/help please, .,.,. and also could it be caused by breathing concrete that he may be breathing from working construction (drilling some sort of holes so it would be concrete dust)is that maybe a possibillity ?

only a medical doctor or registered nurse can really tell you the answer to your question but it sounds pretty serious to me. Bleeding heavily for 20 minutes is frightening and insofar as the other writer is concerned, nausea can result from a nose bleed because you are probably swallowing back a lot of blood - this in itself is dangerous. You can't afford not to see a doctor. It's your life.

For the past month-month and a half i have been getting really bad mucus/flem build up in my sinus canal or built up stuck on my throat between my tonsils. Thing is it's very very sticky to where I can't swallow it or cough it up so I have to use tweezers or my fingers to reach in and pull it out. It's really sticky and stretchy plus very irritating. Don't have insurance with the new job yet so can't go to doctor. So I have no idea whyat is wrong with me. But this morning out of nowhere I started noticing blood in the built up flem/mucus.. Well I went and blew my nose I blew out a big clump of really dark blood. Well I thought it was done after that but I kept tasting blood and sure enough not even hr later there it was again. Another big clump of blood. This time some of the blood come draining down my nose. O yeah and blood only came from one side of nostrils. Well the clumps finally stopped but the blood is still draining down my throat and building up with the built up sticky flem/mucus. Also started getting the world's worst stomach pain. Felt like I got a bat to the belly a hundred times. Please please please any thoughts of what it may be would be very appreciated. Any ideas where I'll have a better idea on what to look up. I couldn't never find nothing online

So when you have a nose bleed it is normal for a clot to come out?

Hi there
My husband had a nose bleed yesterday and then again this morning when he was on he's way to work he freaked out a bit cse this sort of thing never happened to him before so he admitted himself into hospital. apparently they burnt some blood vessel on the Inside of he's nose to stop the bleeding but it got worse he has major blood clots coming out and he feels very weak and light headed. He's also coughing out blood. Please help I'm clueless.
One more thing is It safe for him to sleep on he's back or should he sleep sitting up?
