Hi iv just noticed this morning that I have large purple veins on both sides of my hips and Afew littler red spider veins on my right side. What is it?

Lateral thigh veins. Without seeing this, it could be branches of the lateral subdermal venous system, which is the arc of thigh veins on the upper thigh. When damaged, they become visually prominent. Usually they respond well to injection treatment. They are a cosmetic problem. Have a doctor view them for proper diagnosis.
