Thanks for the query.
If the pain is severe, you once consult gynecologist and get examined for:
-Any possibility of pelvic infection
-If you are having constipation
that can also lead to these symptoms.
Then depending on the symptoms you can go for treatment.
Meanwhile take plenty of water, nutritious diet avoid constipation.
