How Do Cold Sores Cause Lip Swelling?

Cold sores are viral infection caused by herpes virus simplex. The virus enters into the body through broken skin or from abraded mucus tissue of the mouth when a person comes in contact with an infected person. Cold sores are therefore contagious.

After entering in the body, the virus remains latent for a period of time in the central nervous system. It may get reactivated when the circumstances are favorable for it.

Reactivation of virus causes cold sores or fever blisters. The sores develop on lips causing inflammation and irritation.
