Why am I coughing up blood and getting bloody noses out of no where.?

Could be TB, If your coughing up blood, you need to see a doctor, without question

You may have a popped vein and it is bleeding

You need to go to the doctor, there are hundreds of things it could be, I dont want to scare you if it is nothing major. also, Im not qualified, nor do I know anyother symptoms if i did, Smoking that much wont really cause you that much harm. but you need to go to A&E. Hope all is well good luck :) x

Maybe you had a bloody nose while you were asleep and wake up and cough blood, I tend to do that sometimes too. But if it's a large amount of blood, I reccomend you call a doctor!

no calcium, my nose bleeds from nowere all the time especialy in the morning , and when i pick it lol , idk wat to do about it !

Dry air or a low humidity environment can cause this.
