Ranee Boonrung, 9, has suffered from psoriasis for two years, excluding her from the typical child's life of friends and fun someone her age should be enjoying.
The illness affects all of her body causing unbearable irritation.
Ranee, from Yala province in the south of Thailand, first received treatment at Trang's Institute of Dermatology but it was ineffective.
A similar result followed treatment at the hospital in nearby Had Yai.
Desperate for relief for their daughter their parents then tried a two-month treatment programme at Had Yai Univesity but, again, without much success.
But, after returning disappointed to their home town of Yala, her mother said: "We've now heard of a doctor in Buriram who might be able to help the sickness progressing - but the treatment will take three months."
She continued: "We are poor and the cost of travel and treatment is very expensive so we're hoping an appeal on the internet might help our daughter get better".
What is Psoriasis?
Psoriasis is a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales.
These patches normally appear on your elbows, knees, scalp and lower back, but can appear anywhere on your body. Most people are only affected with small patches. In some cases, the patches can be itchy or sore.
Psoriasis affects around 2% of people in the UK. It can start at any age, but most often develops in adults under 35 years old. The condition affects men and women equally.
The severity of psoriasis varies greatly from person to person. For some people it's just a minor irritation, but for others it can have a major impact on their quality of life.
Psoriasis is a long-lasting (chronic) disease that usually involves periods when you have no symptoms or mild symptoms, followed by periods when symptoms are more severe.
