This is untreatable condition and the symptoms appear for a period of weeks or months and then disappear for a while and they appear again later but the condition can be managed and controlled to reduce the duration and intensity of the symptoms.

It can occur in anyone but it usually affects the women belonging to the middle age having fair skin.
