What are the bumps on your upper inner thighs that appear for a while and sometimes disappear or spread grow in other areas?

Keratosis pilaris: a harmless, common skin condition. It causes dry, rough patches of skin that may also be red or brownish. They often appear on the upper arms, thighs, back, and buttocks. It looks like mild chicken skin and isn't usually itchy or painful.

You're more likely to have keratosis pilaris if you have:

- asthma

- hay fever (allergic rhinitis)

- eczema

- atopic dermatitis
