white patches on your skin are a common type of depigmented skin lesion associated with an infection, allergy, or autoimmune disorder. One common cause of white spots, or hypopigmentation, is a fungal infection of the skin known as tinea versicolor (associated with other symptoms, such as itching or dryness on or around the white patches). This fungal infection is not contagious and can be treated easily with over-the-counter medications. Please tell me other symptoms like about sensation on the area, since how long do you have this patch, any family history of white patch, etc.
In the mean time you can take cal phos 6x, 4 tabs twice daily.
Do send me a clear photo of the affected area.
