I have lumpy vein 8 weeks after sclerotherapy treatment! Is this normal?

Superficial thrombophlebitis is common after sclerotherapy and will require percutaneous drainage, warm packs, and massage. Best, Dr. Karamanoukian Los Angeles

The "lumpiness" you are experiencing is due to the "trapped blood" that often occurs after sclerotherapy as well as some inflammation of the vein wall itself, although , by this time, this component is of little significance. Usually, the larger the vein, the greater the chance for this phenomenon to occur. The first visit after a sclerotherapy treatment is typically when this is recognized, and aspiration or removal is recommended. Even after 8 weeks, it is possible to aspirate whatever liquid component remains, leaving the organized (solid) component to be absorbed by the body. Compression stockings can help relieve any discomfort in the leg during the healing process, and should be worn daily until it has resolved.

Following sclerotherapy some veins may clot and form hard areas due to trapped blood within the vein.  Many times these areas will resolve on their own.  Heat to the area and ibuprofen will also help. The alternative treatment for these is to evacuate them with a small needle under local anesthesia.  At 8 weeks I would recommend evacuation and follow up with your treating physician.
