My mother is 63 years old. Her ECG shows she has heart valve blockage leading to less blood supply in some regions of heart. My question is after she walks for a long time in parts of her thighs bluish arteries are clearly visible in thigh and knees. What is this disease called ? Are there information visible in websites ? What are the remedies ? She has her ovaries, uterus removed due to a tumor surgery and she has high blood pressure and suffers from hashimoto’s thyroiditis. She also has cataract operation done on two eyes. What I found out was – The blue you are seeing is most likely veins, not arteries and are more prevalent due to decrease in her heart function. She needs to bring this up with her doctor on her next visit.
