Cold Sore

The one who usually treats cold sores is the dermatologist, though the general practitioner can also guide simple cases; it is a very common viral infection that causes small painful blisters around the lips.

Common causes: It is caused by a virus that remains dormant in the body and can reactivate with stress, fever, sun exposure, or a weakened immune system.

Common symptoms:

• Tingling or burning before the lesion appears
• Clustered blisters that later form a scab
• Passing local discomfort

When to see a doctor? If the outbreaks are very frequent, painful, or do not heal, it is worthwhile to have it checked. A review with the specialist helps understand the triggers and take better care of the skin.
