Suggest Treatment For Severe Headache,body Pain And Dizziness

Doctor, My boyfriend (21 years old) is having a sever headache since along time. He had asthma and now his hands shiver when he work or write. When he get confused or in a problem, he gets fever quickly and his nostrils starts bleeding. He complaints about flashes in front of his eyes, feeling dizzy and constant aches in his body. Most of the time he is under great pressure due to family problems. He stay up at nights and complain he's not feeling sleepy. Is this due to his mental stress or is it a side effect of long term asthma medication? How can I help him to recover this situation? Please help me with my problem.
