I can appreciate your anguish. Few years ago, I developed dermatitis on my face - never had it before in my life before and it was bad. I started to look like a lumpy-faced teenager. Not very pretty on a 25 year old woman! Went to doctor, got standard treatments, should be all solved. Problem: low percentage of people react to the standard medication, causing the dermatitis to clear in the short term, but be exacerbated in the long term. Result: problem got 10 times worse. Finally, referral and 3 month waiting for an appointment to see top dermatologist, my hero, who took one look and said, stop using that other stuff, use this stuff instead. All gone in 1 month, never to be seen again.
My advice, if you have not done so already, go see an expert.
