Complications – Normally, there won’t be complications, even if left untreated, except that it will spread more. But if maltreated, complication can arise from drugs. Since there is no 100 per cent guarantee or sure cure in any system of medicine, people often go on with drug cocktails from various systems of medicines and doctors. This mode of treatment often brings drug effects or side-effects. Likewise, people often go for external application, dyeing, bleaching, etc., which make the skin more sensitive and cause infection or boils. Everyone knows that being in the hot sun make one’s skin darker. In the case of leucoderma patients, it will be more, i.e., extreme darkening of the skin and sunburn. Excess exposure to the sn even for treatment purpose, may cause blisters, ageing of the skin, wrinkling and extreme darkness of the skin. Also, if they had previously tolerated the sun (while having a sunbath), it may become intolerable when they suffer from leucoderma. Itching red rash or blisters may develop due to polymorphic light reaction of the sun. Everyone should be careful about this as sunlight is a leading cause for skin cancer. Leucoderma can reflect in the mind, causing psychological fears, emotional upset, shame, and socio-behaviourial changes by trying to avoid being in the public, attitude of others who insult by avoiding contact. These changes restrict their social behaviour and communications. There may also be fear of ugliness, fear of hereditary (infecting the generation), contagiousness, other diseases, cancer, etc.
