What is the Surah mentioned in the noble Quran that is used as treatment for headaches and to stop bleeding?

All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

For the treatment of headaches, it was narrated on the authority of Abu Hurayrah that he said, "When Revelation descended upon the Prophet, sallallaahu ‘alayhi wa sallam, he would suffer a headache, and he would wrap his head with henna." [Ibn As-Sunni, Abu Nu‘aym in At-Tibb; As-Suyooti: inauthentic]

It was also narrated that during his death sickness, the Prophet, sallallaahu ‘alayhi wa sallam, said, "O my head!" and that he used to tie a headband around his head during sickness. [Al-Bukhari]

It was also narrated that nobody complained to the Prophet, sallallaahu ‘alayhi wa sallam, of a headache but that he (the Prophet, sallallaahu ‘alayhi wa sallam) ordered him to do hijamah (cupping). [Al-Bukhari in At-Tareekh, Abu Dawood]

As for the treatment of bleeding and wounds, it was narrated that when the noble face of the Prophet, sallallaahu ‘alayhi wa sallam, was wounded on the day of the battle of Uhud, washing it with water did nothing but increase his bleeding. So Fatimah took a piece of straw mat (made of papyrus), burned it until it became ashes, and put it on the wound whereby the bleeding stopped. [Al-Bukhari and Muslim]

Moreover, it was narrated that when a man experienced pain or suffered an ulcer or wound, the Prophet, sallallaahu ‘alayhi wa sallam, would point with his finger in this way (Sufyan, the narrator, put his forefinger on the ground and then raised it to the sky as describing what the Prophet, sallallaahu ‘alayhi wa sallam, did) and say, "Bismillaah, turbatu ardhina bi-reeqati ba‘dhina, yushfa saqeemuna, bi-ithni Rabbina." (In the Name of Allah, the dust of our ground with the saliva of some of us would cure our patient – with the Permission of our Lord.) [Al-Bukhari and Muslim]

As far as we know, there is no proof that indicates that there are specific verses that are used in treating certain diseases. However, the Quran in general is a cure. Allah says (what means): {And We send down of the Quran that which is healing and mercy for the believers.} [Quran 17: 82]

It was also narrated that the Prophet, sallallaahu ‘alayhi wa sallam, said, "The best medicine is the Quran." [Ibn Majah] [As-Suyooti: inauthentic]

Allah knows best.
