Hello doctor! I am 21 years old this year, my legs have varicose veins since childhood. Now the leg is swollen and forms hard lumps like lumps, painful to the touch. The top of the pillow is bulging and when it hurts, the blood vessels are very prominent. This morning when I woke up, it was very painful and throbbing and I couldn't straighten my leg. Can you advise and tell me how to fix it? I thank you!
