Thank you for your query.
The description provided by you suggest that the veins can be varicose veins
or just prominent veins. If the bulge disappears on pressing the veins then the veins do not have thrombophlebitis
. As your parents had cirrhosis
of liver it is advised that you get yourself examined and even get an ultrasound
of the abdomen to know the condition of your liver.
It is good to know that you have given up smoking
and are keen to be more healthy by reducing your BMI level. Wish you all the best for it.
I hope I have responded to your query to your satisfaction.
