typically umbilicated vesicles, painful, that unroof and crust over
typically localized to the vermillion border
Prodromal (day 0–1): Tingling, itching, and reddening of the skin around the infected site
Inflammation (day 1):  Swelling and redness
Pre-sore (day 2–3): Tiny, hard, inflamed papules and vesicles that may itch and are painfully sensitive to touch.
Open lesion (day 4): Vesicles break open and merge to create one big, open, weeping ulcer. May develop a fever and lymphadenopathy
Crusting (day 5–8): A honey/golden crust starts to form from the syrupy exudate.
Healing (day 9–14): New skin begins to form underneath the scab.  A series of scabs will form over the sore (called Meier Complex), each one smaller than the last.  Irritation, itching, and some pain are common.
Post-scab (12–14 days): A reddish area may linger at the site of infection.
