Beach sand makes me itch and I spend the afternoon scratching my feet (3)

Description: I went out to the shore of the beach to play with the sand and my bare feet, however this sand apparently had something that my skin could not resist because when i got there and touched it, a great itch began to immediately start. i sat down to use the long nails of my hands and with these scratch myself and thus stop the itching a little, however it did not decrease and it spread throughout my body so i continued and continued scratching myself.
