thank you for your query.
the swelling in clitoris
is due to edema or collection of fluid.edema is common in pregnant women because during pregnancy
women retain more water. That water can collect in the extremities and cause uncomfortable swelling.this is called edema in dependent parts(most affected by gravity parts)
The affliction tends to begin around the fifth month of pregnancy and can increase due to various external and internal factors.
1.reduce salt intake
2.drink lots of water
3.foot end elevation and avoid standing for more than 20-30 mins
4.exercise in moderation such as yoga
5.keep your BP under check all times.
6.wear accomodative clothing.
wishing you good health
