Thanks for choosing health care magic for posting your query.
From the description that you have given, it appears that you are about to develop varicose veins
. The bluish discoloration that you are describing can be the initial stage of varicose veins. However final comment can only be made by examining you or by seeing a snap of the lesion. This condition appears cause of excessive standing. You should sleep with legs elevated and wear elastic stockings at work. Doppler ultra sound
can give a definite diagnosis.
Hope I am able to solve your concerns.
If you need any further help in detail, I will be more than happy to help you.
Wish you good health.
