Chronic venous insufficiency: What is Donald Trump's health condition

A few days ago, photos zooming in on US President Donald Trump's swollen, bruised hands and ankles were doing the rounds on social media, giving rise to speculations that he is not well. While many said that it looks like oedema, signs of cardiac conditions or sleep apnea, the White House has now put the rumour to rest. White House Press Secretary Karloline Leavitt said that the president is suffering from a condition called 'Chronic venous insufficiency.' The press secretary said that it was confirmed after Trump underwent vascular testing. According to the White House physician, it is quite a common diagnosis among people above the age of 70. 

Why does it happen? 
When our leg veins are damaged and can't work correctly, it can result in Chronic venous insufficiency (CVI). CVI damages valves that take blood to the heart, causing it to pool in the legs and increase pressure in the veins, which can lead to ulcers and swellings. 

Symptoms of CVI
1) Leg cramps at night
2) Tired, achy legs
3) Tingling pins and needles sensation in the legs
4) Varicose veins
5) Open sores or ulcers near your ankle
6) Itching of the skin on feet
7) Heavy feeling in the legs

How is it treated
Treating CVI requires lifestyle changes, compression therapy, leg elevation, exercises, the use of compression stockings, and proper guidance on related issues from your doctor. Intermittent pneumatic compression (IPC) is also administered to some patients who can't wear the stockings.
