You seem to have dryness in the genital tract. The tissues in the region are dry and hence the burning sensation during urination. I hope you are hydrating well.
Dryness is because of inadequate female hormone called Oestrogen. Since you already attained menopause
it is premature. If I am right you have the same problem during the intercourse or after intercourse. It can be a systemic problem and you may have multiple system problems like gastritis
, skin issues etc.
You should check with an Endocrinologist
