I have gone through blood test in month march. I feel tired all the time. I faced severe hair fall and after that i have noticed a white patch on my nose. After consulting doc i came to know its P alba. I did not find alopathy treatment working for me. I went for homeopathy treatment. Its still going on.. But i guess it's also notworking.In reports I found vit b12, vit D and iron deficiency. I need consultation from good doctor who can solve this problem from root and find the cause behind it. And yes i feel whenever i take stress my problem get increase. My white patch became more prominent.
