Brief Answer:
sit with your leg raised, raise the leg end of the bed

Detailed Answer:
Hi
Welcome.

High blood pressure makes your heart worker harder. Long standing hypertension, affects the heart, and is less effective at pushing the blood around. This allows fluid to build up in your lower legs and ankles, which causes them to swell up.

I would suggest you to sit with your leg raised or lifted up, while sleeping also raise the leg end of the bed or but pillows below the leg. This lets your blood flow more freely and should help reduce the swelling.

Please also consult a cardiologist and get lipid profile test done to know if you have high cholesterol in your blood. It is better to get a complete heart check up done because as said earlier high blood pressure also affects the heart.

Hope this helps.
Take care.
