I get them ever couple of months. Heres what you do. FOLLOW THIS
1. Get Abviva
2. Put it on your giant ass cold soar DIRECTLY FROM THE TIP
Don't use your finger because when you do, your getting whatever is on your finger on your coldsoar. Also your finger soaks some of it up.
3. Let it sit in a big glob on your coldsoar until it disolves, then do the same thing over, for at least a day or two.
In 1 day you'll see a huge improvement. In 3 it probably will be almost gone or not noticable.
