so my first two weeks i took 40mcg a day of clen, took a week off. I started again about a week ago this time planning on increasing a few days into it but i got this irritated looking rash on the left side of my kneck. I'd say it takes up about 30% of my kneck and its defenitely noticably red, not only that but it swells up a good amount making me think its not topical. I'm on acne pills(not accutane) and i use all sorts of creams but not on that particular part of my body. the rash only appears post-workout for about a hour then goes away in about a hour. I'm going to the doctor but i can't mention the clens, i'd like to know if anyone has ever experienced something like this before?
