my child has been suffering from white patches since 3 yrs.I took her to PGI hospital Lucknow but the treatment was not satisfactory.the effect of the medicine was that on application of the medicine one side of the patch recovered while discovering similar patches on the other part around the recovered part.these days according to doctor s advice she is undergoing phototherapy.actually i am not satisfied with the doctor s treatment.He himself is sceptical about the problem.she has already undergone photoatherapy for one month and during those days she was asked not to take medicines anymore.but that had almost no effect on her except some minor indications.And now he has advised to continue medicine alongwith light-therapy.would u please kindly suggest me on this matter.please advice me on what to eat and what not to eat.
