The only source of information you should be consulting is a specialist dermatologist on referral from your GP.
Self-serve information has been shown to cause people anxiety and drive them poorly informed spurious conclusions, all because they are thinking the knowledge they trawl for and gain from the internet is better than a 20 minute consultation with a Doctor. It's not. This is a major problem being seen by Doctors the world over, "self-serve", including those who delve into PubMed, Medscale and university research journals. I note that the author of the article in Cheeseslave says "I am not a Doctor".... yet speculates wildly in all directions and seeks discourse. That discourse is speculative, conjectural, indirect and in a lot of places, heresay, towing the line of of populist opinion rather than proven science.
