Is the hadith that came concerning the merit of headaches for the believer authentic?

The questioner did not quote the specific text of the hadith, but there are hadiths that mention the virtue of headaches and illnesses in general. Among them is the hadith: "Whoever suffers a headache in the way of Allah, and then endures it patiently hoping for Allah's reward, Allah will forgive him whatever sins he committed before that." And the hadith: "No vein throbs in a believer except that Allah thereby removes a sin from him, records a good deed for him, and raises him a degree." Both indicate the virtue of headaches and pain in expiating sins and raising ranks. This is supported by the general texts regarding the virtue of trials, such as the hadith: "When Allah desires good for someone, He afflicts him." And the hadith that states if a servant has a high station destined for him with Allah, but he does not reach it through his deeds, Allah afflicts him in his body, wealth, or child until he attains it.
