Had coldsore & put abreva on right away. it was healed over in 9days but has left a bright red circular spot another 10days. is it actually healed?

It's healed, but...: If the red area is intact (no open sore or scab) your outbreak has healed. It can take a few weeks for redness to fade. FYI, Abreva is ineffective; your cold sore probably didn't heal any faster than it would anyway. Speak w/ your doctor about prescription for valacyclovir (Valtrex®) to have on hand. One dose by mouth, as soon as an outbreak starts, is very effective, a lot faster than 9 days.
