Then the doctor tightly tapes a cotton ball over the injection site. One injection helps only about an inch of spider vein, so you'll probably receive multiple injections in a session. A session takes anywhere from 15 minutes to 45 minutes. Often, however, the vessels need to be treated more than once. Typically, patients need about three to five sessions, each separated by a month.
Special stockings aid the process.
After your treatment, you need to keep the taped cotton balls on for about 24 hours. You may also need to wear tight elastic bandages or stockings for three or more days. You may feel some slight cramping or soreness near each injection site for a couple of days. Generally recuperation is a breeze. Most people can resume normal activities right away, but you should avoid exercise for about 24 hours.
