Is trimming excess eyebrow hair that obstructs vision and causes discomfort considered the prohibited plucking (namṣ), and is there any objection to removing excess hair from inside the nose and ears that causes discomfort?

There is no religious impediment to removing excess hair from the eyebrows or other areas, especially if it obstructs vision or causes harm or embarrassment. Similarly, it is permissible to remove hair from the nose and ears in all cases for those who wish to do so, because it is among the unmentioned matters, and perhaps its removal is more appropriate, especially nose hair for the sake of cleanliness.
