Sclerotherapy at a top Park Avenue clinic

I had sclerotherapy at a top Park Avenue clinic, very well known and highly touted. They completely ruined my legs. What was initially a tiny little area of light spider veins became a large, extended area of dark angry spider veins following the treatment. I was told it was an allergic reaction to the solution, commonly seen in fair skinned redheads, and unexpected for me since I am a medium tan skinned hispanic. I was told to return & that "blitzing" it with additional doses of the solution would clear it up. Baloney! It got even worse, my entire leg is now full of dark veins and it has been at least 4 years with no "clearing up" ocurring. Beware!
