My legs feel heavy and my feet are swollen, I'm worried it might be varicose veins.

These days, my legs feel heavy even after just a little walking. My feet are always swollen when I wake up. I thought it was just due to accumulated fatigue and my diet. But the symptoms haven't improved and continue persistently. Considering my age, I worry even if there's a slight abnormality in my body. Health is the most important. Everyone, take good care of your health.
