i am writing for a friend, he is 22 yrs old. and recently on flight he experienced severe eye pain, like his vein was going to burst or something, he had a headache the whole day after the journey.
the next day, he said he was spitting out blood for like the whole day. he says it seems like it arises from his nose or above. he also said he was sneezing a little before flight. i do not recall his body weight, but he is about 5'9" and weighs normal, not overweight.
