you sound like me at about my day 15 point in all your symptoms except i as having an eczema breakout instead of acne. the encouragement i got was to keep going and just ride it out... your body must really by detoxing and that's why the Acne is getting worse.
i'm not sure if you should be worried that the scarring will be worse though... there's been a few posts lately about how fasting really does heal the skin, INCLUDING healing scars and stretch marks.
