Hi Darla,
My sister is a dermatologist (comes in handy). When she was in med school, she injected my spider veins with saline solution (sclerotherapy sp?). It hurt like heck, and it didn't work. I had to wear an ace bandage over the site of the injections for a while-it helps to make sure they go away. Now that she is a full-fledged derm, she has a laser at her office, and has lasered them a few times. It hurts a lot (like a rubberband being pulled and snapped on skin), but it works a lot better. Because it is so painful (even with Lidocaine to numb the area), I go back once or twice a year for her to zap more of them. I have noticed a big difference with the laser, and I would say that for a short time of pain, it is worth it.
