Hi - my skin by my feet and ankles has red swollen marks which are very itchy. My guess is that it's from insect bites at dinner the other night. My pharmacist recommended cortisone 10 which is a 1% hydrocortisone anti-itch cream which says on the label that its itch relief is 10 hours. While this works initially (say for an hour) my skin remains itchy and at night when I am trying to sleep, the itching keeps me awake. Any thoughts?
