Is micro-sclerotherapy painful?

Micro-sclerotherapy is a minimally invasive and relatively painless treatment for spider veins and small varicose veins. A small prick from the injection needle is the only thing that can be felt, sometimes followed by a brief burning sensation as the sclerosant successfully attacks the walls of the affected veins. The needles used for micro-sclerotherapy are much finer than those used for taking blood.

Sclerotherapy does not require any anaesthetic for this reason, but also because no heat is used and there are no surgical incisions that have to be stitched or clipped. Nor do you have an operation scar afterwards.
