What are these strange white flaky plaques on the side of my nose? how do i get rid of them? they pop up especially after shower. feels "hot."

Flaky skin: It may be seborrhea or eczema or simply dry. Best to try gentle cleansers and moisturize. If that does not help a dermatologist may prescribe topical creams.

Rash around nose: The most common scaling or flaking rash that appears around the nose is seborrheic dermatitis, related to dandruff on the scalp. Often the scalp and the area around the nose are inflamed at the same time. Seborrheic dermatitis is a chronic skin condition that cannot be cured, but can be controlled with topical medications. Gently washing with an anti-dandruff shampoo helps improve the rash.
