Dear ptn.,
There are chances that it is due to hormonal. To confirm it we need to do the blood tests.
Before that we have to rule out other causes. E.g.
1. Constipation
2. Any allergies
3. Skin infection
Without examination can't advice kumari aasav to her due to her age.
Thank you.
Next Steps
rule out above causes.
