What causes fever blisters?
A fever blister located on the lips, mouth, and face is usually caused by the highly contagious herpes simplex type 1 virus. Only a small number are caused by herpes simplex type 2, the type usually associated with genital lesions.
There is no cure for a fever blister. However, there are medications that will relieve the pain and itchiness, and speed the healing of the blister.

Reader: I got a bad sun burn and now it's painful. How can I tell if it's just a regular sunburn or if it's sun poisoning?
Sunburns are never good news. Not only do they leave you red-faced and stinging, but they often leave lasting damage. Sun poisoning may seem much more serious, but it's essentially the same thing. In medical terms, sun poisoning and sunburn are both referred to as photodermatitis, your skin's allergic reaction to overexposure to the sun.
In the case of sun poisoning, however, the reaction is a bit more severe and the symptoms may become seriously uncomfortable. A typical sunburn involves itching, redness, and peeling. Severe sunburns may also be accompanied by small blisters that may lead to infection. Symptoms of sun poisoning also tend to include nausea, fever, headache, and dizziness and may also be accompanied by fluid loss and electrolyte imbalance.
If your symptoms are limited to mild discomfort, treat your skin the way you would treat a...
