It was narrated from Jabir:

That the Prophet was treated by means of cupping when he was in Ihram for a contusion that he had suffered. (Diaf)

أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ بْنِ الْمُبَارَكِ، قَالَ حَدَّثَنَا أَبُو الْوَلِيدِ، قَالَ حَدَّثَنَا يَزِيدُ بْنُ إِبْرَاهِيمَ، قَالَ حَدَّثَنَا أَبُو الزُّبَيْرِ، عَنْ جَابِرٍ، أَنَّ النَّبِيَّ ﷺ احْتَجَمَ وَهُوَ مُحْرِمٌ مِنْ وَثْءٍ كَانَ بِهِ .
