Psoriasis most commonly affects the knees and elbows, but it can show up anywhere on your body, including the scalp, nails and genitals. It can look like patches of thick, red skin covered with silvery scales. The inflamed patches (called plaques) can itch or feel sore.
In general, these are the five types of psoriasis and their individual symptoms:
- Plaque psoriasis: The most common form, with red patches and silvery scales.
- Guttate psoriasis: Teardrop-shaped small spots on limbs, trunk and scalp.
- Pustular psoriasis: Small, pus-filled lesions adjoining active plaques.
- Inverse psoriasis: Patches in skin folds of armpits, genitals and breasts.
- Erythrodermic psoriasis: Widespread reddening and scaling of the skin.
