Dear Dr. Prasad, I have been suffering from Vitiligo patches for more than 25 years. Those patches were stable. Those patches are located on joints like both knees, both elbows and both thighs. Last eight years, i am on homeopathic medicine and still there is no substantial change in these patches. In last two years, i have lost my sister and father and now i am seeing much more faint patches (which possibly can grow in dark white). I am really worried, nervous and depressed. Can you please tell me what shall I do? Thank you for your opinion in advance.
