I've never had anything like this on my back before, 20-30 tiny little pink bumps appeared on my waist and wings, it looks like a pimple. Very rarely, once or twice a month, I had a big pimple on my back shoulder, but I've never encountered such a thing. In the past, even when I was a person who consumed a lot of protein, it would not come out, although I consume 150 grams now, there is such a situation. I've been using creatine for two months, I'm using 3 gr, 2 scoops of whey a day, I'm using zma. I drink about 3-4 liters of water a day. My macros are fine. Is this acne related to my diet?
