itchiness, post-partum

ever since i had my LO, the bottom of my left foot is very itchy (specifically my left foot). it is a weird place to have itch, since it is the "palm" of my foot. it has been like this for a full month. my parents think it is a result of the epidural and possibly a nerve that was impacted by the epidural. anyone experiencing anything like this? i will ask my dr. at the 6week post partum exam.
