ANSWER:

There is no hadeeth stating that clearly. 

The hadeeth doesn’t indicate that the man is in hell just because he doesn’t have headaches! It indicates that headaches are a good sign of the people of Jannah as they are being tested. 

Ysday I came upon a Hadith that says, Rasul Allah ﷺ asked a person,”Have you ever felt a headache?” And he replied,”what is a headache?”.So Rasul Allah ﷺ said”Whoever would like to see a man from the people of Hell, then look At this man”. Also a person who doesn’t suffer from headaches is destined to go to hell. And Headaches are a means of forgiveness and reward. Pls clarify
