My left leg began to have patches of ulcers with liquid flowing out.
Went to NUS and doctor believed it is due to blood retention in my ankle.
In a normal person, blood are pumped and flowed into the legs.
Due to gravity, when blood are been pushed upward towards the heart, a knee valve will closed to prevent blood from flowing downward back to the legs.
Through a sonic scan, they found a weak knee valve which is not able to close 100% and leaking blood back to the legs.
Doctor prescribe a special leg compression stocking to be worn daily, where it helps to push the blood upwards.
