You seem to have developed an allergic reaction. Apply momate F cream thrice a day for three days and then twice a day for three days. Take tablet Xyzal 10 mg twice a day for one week. However I would recommend getting the reaction properly assessed by a qualified dermatologist. You can send pictures via online consult if you want. Because if the reaction is a little more severe you might also need some additional tablet which currently prescribed without proper examination. Hope this is helpful.
