Hi, Going through your elaborate history, I am of the opinion that the rise in white blood cells is due to you recent infection. If you have got your CBC report you can check, the neutrophils are increased more than others. It is not leukemia, as leukemia would have very high or very low cell count. If there were any immature cells indicating leukemia, CBC would have definitely found out. You are probably getting frequently sick due to reduced immunity secondary to nutritional vitamins and mineral deficiency. Vitiligo is not connected to all this. However, in nutritional deficiency of B group of vitamins, whitish patches are seen in arms and legs. Improve your nutrition either with supplements of B complex vitamins and minerals and wait for improvement. You can meet a dermatologist for confirmation of vitiligo. A skin biopsy might be necessary for confirmation. Any further queries, happy to help you again.
