Is Sclerotherapy Painful?

Is sclerotherapy painful? A varicose vein doctor at Emory Vein Center explains:

Sclerotherapy is closing a vein using a medication, using a solution that we inject into the vein to irritate the lining of the vein and cause it to close down.

It’s a little bit uncomfortable. It is small needle sticks like big mosquito bites. It’s not like getting shots in your arm, but there are a number of small pinpricks.
