In the photograph that made Kim Phuc a living symbol of the Vietnam War, her burns aren't visible - only her agony as she runs wailing toward the camera, her arms flung away from her body, naked because she has ripped off her burning clothes.

More than 40 years later she can hide the scars beneath long sleeves, but a single tear down her otherwise radiant face betrays the pain she has endured since that errant napalm strike in 1972.

Reunited with photographer, Nick Ut - the man who made her suffering the indelible image of the Vietnam War and helped turn the tide of public opinion in the United States - she has travelled to America.

Now she has a new chance to heal - a prospect she once thought possible only in a life after death.

"So many years I thought that I have no more scars, no more pain when I'm in heaven. But now - heaven on earth for me!" Phuc says upon her arrival in Miami to see a dermatologist who specializes in laser treatments for burn patients.

Late last month, Phuc, 52, began a series of laser treatments that her doctor, Jill Waibel of the Miami Dermatology and Laser Institute, says will smooth and soften the pale, thick scar tissue that ripples from her left hand up her arm, up her neck to her hairline and down almost all of her back.

Even more important to Phuc, Waibel says the treatments also will relieve the deep aches and pains that plague her to this day.

Waibel has been using lasers to treat burn scars, including napalm scars, for about a decade.

Each treatment typically costs $1,500 to $2,000, but Waibel offered to donate her services when Phuc contacted her for a consultation.

Waibel's father-in-law had heard Phuc speak at a church several years ago, and he approached her after hearing her describe her pain.

At the first treatment in Waibel's office, a scented candle lends a comforting air to the procedure room, and Phuc's husband holds her hand in prayer.

Phuc tells Waibel her pain is '10 out of 10' - the worst of the worst.
