I really get amazed why patients approach google before approaching a qualified certified doctor who has spend years in training and acquired specialised skills and expertise after years of experience. you should consult your doctor and then may be read about the medical condition to be more informed about what you are suffering from rather than scaring the wits out of yourself by coming across scary condition which you might not even have. To make a diagnosis proper examination would be needed. and after assessment if there is a dilemma on diagnosis a biopsy can be considered. Without examination of the skin condition and knowing the extent of involvement.. along with this more information on ongoing medication or history of previous/current skin/systemic illness it is not possible to comment on the treatment that would suit you best. You should send me images through private online consult for a better assessment of the problem and approaching it accordingly. Hope this is helpful.
