Thanks for the query,
You have developed an allergic reaction
to the cream.
Treatment can be with mild steroid,
Please stop the cream which you are using presently.
Apply a mild steroid lotion like desonide
Also take an antihistamine tablet like cetrizine
This will give you some relief.
Please meet a dermatologist
for exact diagnosis.
