The Prophet ﷺ forbade to cauterise; we cauterised but they (cauterisation) did not benefit us, nor proved useful for us. Abu Dawud said: He used to hear the salutation of the angels: When he cauterized, it stopped. When he abandoned, it returned to him.

نَهَى النَّبِيُّ ﷺ عَنِ الْكَىِّ فَاكْتَوَيْنَا فَمَا أَفْلَحْنَ وَلاَ أَنْجَحْنَ
