Fever blisters (or cold sores) are painful sores, which occur on lips, cheeks, chin, fingers, nostrils, or even genitals. These are caused by a virus, named ‘herpes simplex’. Fever blisters are contagious and are usually mistaken to be canker sores (which are actually mouth ulcers and occur inside the mouth). Several cures are available for soothing and healing fever blisters. Before going for any medication, you can also use the home remedies for fever blisters or ingredients from your kitchen counter to get rid of the fever blisters.
