Swollen and painful branch vein after sclerotherapy. What could that be?

It is not uncommon for a branch of veins to be swollen and painful one week following sclerotherapy treatment.  The solution was instilled into the veins to shut them down.  Depending on their location, for example, the ankle or back of the knee are not able to rest when continuing with normal daily activities.  Continue to monitor the treatment site, wear support hose, and take Tylenol or Motrin as needed.  If the area becomes reddened, contact your sclerotherapy provider. 

Thank you for posting your question.Clinical judgement is important when performing sclerotherapy for 'large branch veins' as the alternative treatment of microphlebectomy precludes development of thrombophlebitis, which is very symptomatic.Topical heat and ibuprofen can help with your symptoms of pain and tenderness.BestDr Karamanoukian

It is fairly common to have some tenderness after sclerotherapy. It is best treated by wearing compression stockings, using warm compresses and taking ibuprofen as needed. If you have true pain or persistent swelling, I would follow up with your treating physician. Take care!

Following sclerotherapy of larger veins clotting can occur in these veins and it will usually occur about one week after the treatment.  If this occurs the best treatment would be to evacuate the clotted blood with a small needle.  This can be done with local anesthesia.  In addition, wet heat to the area and ibuprofen would help.  Follow up with your treating physician.
