My dad is 49 years old. He's always busy with his work (he's a chef) he comes home around 10:30pm and he goes to sleep around 12am. He's starting to have major headaches for about a week now. He refuses to see the doctor cause he doesn't have time, (I will keep pushing him to see a doc) but I'm worried.
When he gets those headaches, it's the whole day. I feel his pain, and I am worried since I am his daughter. He has a lot of stress and lacks sleep. Is this a sign of any diseases? Like leukimia? Brain tumor? Please let me know!
I thank you in advance! :)
