After reading your history it appears that you might have developed dependence of steroid
cream ofter long term usage. I advise you to not use the cream as it is quite strong cream so can cause thinning of skin and mutiple other side effects. Do not pinch or pop the area. You can apply a mild potency steroid cream such as cortisone
cream to take out from the side effects slowly. If itching is present then can take benadryl
accordingly. Apply a plenty of moisturizing cream to reduce the other side effects. IN between consult a proper dermatologist
who can treat the condition better.
