Treating kidney pain

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, pain in the flank is (an affliction of) the vein of the kidney; when it stirs, it causes pain to the one who has it, so treat it with boiled water and honey."
This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) had cupping done and gave the cupper (hajjam) his wage, and he (peace and blessings be upon him) also put medicine into his nose.
This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it with this addition.
