Thank you for your query at DoctorSpring.com
I understand your concern.
From the picture, it is difficult to make out any venous dilatation.
You do not have any symptoms suggestive of DVT, as in DVT the pain is severe and increases on exercise.
It could be due to a long standing varicosity, which can be confirmed only on physical examination.
Do you have any history or Hypertension/ T2DM? What is your profession? Do you have to stand for long periods of time? Can you feel any venous dilatation around your calf/ thigh region?
Please feel free to discuss further,
