Hi there young lady...
Continuous itching should be looked at and a more detailed history will be needed to evaluate and assess this further.
Given your stated weight is 82 kgs at a height of 5.1 ft, then your BMI is not under the normal curve and there may be some hormonal issues at play here.
Since the itch is in a sensitive location, kindly send pics 📥 and opt for an Online Consultation 🙏
No it's NOT 🚫 oK to use this cream on the nipples etc and definitely not for a prolonged time and without a prescription from a qualified doctor.
