Browny spreading patches & marks on face

From last few months i am getting brown coloured marks and patches on my left side of the face. Amd i have been observing it to b spreading from last few days. I have consulted 2 doctors in regard of dis condition and they have asked d me to burn the patches. One of the doctor even told me that its a type of viral infection and have prescribed some ointments and tablets and also told that even after the medication, if the problem m is still persisting then to burn the patches on my face. I am really struggling very hard with this present problem. I am really helpless and so worried about it because day by day the marks are getting more on my face and its leading to loose my confidenc level to the extreme. Kindly help me out by finding some solution for this.
