Concern) Chronic lower limb edema

The symptoms of persistent swelling, heaviness, and numbness in my legs are chronic.

I have undergone two procedures at the hospital. I had two laser treatments to remove blood vessel blockages. Blood circulation should occur, with blood flowing from the legs to the heart, but there are blood vessels that can't carry blood upward, so I had procedures to remove them. I also take two months' worth of medication, but there is no improvement; everything remains the same. The doctor said it's just chronic and to manage it lifelong. But I don't know what that management entails. They told me to exercise, but even walking a little causes severe leg pain, and I end up limping.ㅜㅜ

I really want my leg to get better. 😢
