Does sclerotherapy cause any damage or side effects? |
|
As with all medical procedures, side effects and complications are possible. This is why it is important to seek treatment from an experienced physician. Allergic reactions are extremely rare and mild such as a rash when they do occur. They are somewhat more likely to occur when treating larger varicose veins because the medicine is more concentrated and used in greater volumes.
A mild, temporary increase in pigmentation (staining of the skin) may occur if you have any of the following: darker skin, overly sensitive skin, very dense spider veins, or if your skin is already damaged because your veins have deteriorated too much.
Sometimes when the vein is collapsed pockets of blood may be trapped in the injured vein (trapped blood). Trapped blood can cause a little discomfort and is treated by gently removing it with a syringe.
Rarely some of the sclerosant may escape from the vein wall and cause a slight burn injury to the skin which can heal with a chicken pox like scar.
