A lot of goose bumps on the legs could be periorbital keratosis. This is because the congenital manifestation of peri-hair keratosis is keratinization or hyperplasia of the hair perimeter, which then forms a kind of keratotic papule with follicular consistency. This keratotic papule is usually accompanied by varying degrees of itching and dryness. If it is prolonged, it may be accompanied by localized hyperplasia and hypertrophy of the skin. This goose bumps is actually a hereditary skin disease that is generally dominant, meaning that at least one parent may have this clinical manifestation. Therefore, the disease can only be relieved, not effectively eradicated.
