Help!! My boyfriend won't be told😞

My boyfriend has been having loads of nosebleeds recently, in which he has been loosing large amounts of blood and been really poorly with them.
I want him to have a blood test to see what the cause of the problem is, but he is terrified of hospitals and is refusing any sort of help! I really want to know what's happening, I'm worried, but he just won't budge🙄
