Is it permissible to pray with blood inside the nose if it only rarely comes out, knowing that its removal takes a significant amount of time and effort?

Impurities inside the nose must be washed, as the nose takes the ruling of the external body, due to the gravity of impurity. Therefore, one must wait for the bleeding to stop and wash it before praying, unless the prayer time is about to expire. If the bleeding continues and does not stop before the prayer time expires, the prayer is valid despite its presence. As for past prayers performed with the impurity due to ignorance, there is no need to repeat them.
