Hi Pooja, welcome to HCM.
It would have been greta if you had mentioned the exact symtoms and the places where there are white spots
so that we could determine the case exactly. However, considering the spots on your hands and fingernails, it is possible there is iron or zinc deficiency
. Include a lot of green leafy vegetables, other vegetables and fruits as much as possible. Also, you can check with your doctor for a multivitamin
tablet to suit the needs if required. Also, since you say there are chances of it being fungal, i would suggest you to consult a dermatologist
and take the best medication.
