Hii ...milia are subepidermal cysts arising from the small hair follicles that are usually seen on face . It can occur anywhere and is assymptomatic . The white bump inside the nose could be milia but will have to see the lesion to confirm .
Next Steps
If it is milia, then it usually disappears on its own in 3-4 weeks . U don't have to do anything. But if it is bothering u then u can consult a dermatologist and it can be removed.
Health Tips
Just leave the lesion untouched if it doesn't bother u and if it looks like the other milia lesions
