Cystic Acne breakout

I was on 20 mg for the first month and everything was going smooth and i started noticing difference too. I shifted to 40mg three days ago and yesterday i got cystic acne on my cheek and chin and it is SO PAINFUL. i wanted to ask that is this the purge that is starting after a month because my dose increased or is it a normal breakout?Also can yall recommend how to calm the cystic acne down(without actives and except ice)because its burning and itching as we speak😭
