For sclerotherapy a medication called Asclera (polidocanol) is administered into the spider vein with a tiny needle. The medication causes the vein to contract and eventually disappear. As with all medications, some patients could experience a reaction to the solution; however, this is extremely unusual and treatment is usually well-tolerated. Follow up with your vein specialist if the changes you are seeing worsen or if there is pain and/or swelling.Treatment response can vary for different patients, but in general they are all typically temporary. Also, treated areas may cause micro veins appear, a known side effect called matting. If this occurs, another treatment of sclerotherapy session may be needed. Always, avoid strenuous exercise and weight lifting for 1 week after sclerotherapy session and wear compression stocking for a period of 1 week.

All the best and good luck!

Yes. It may be lumpy for a few weeks to a few months. It simply means the vein is treated and there is probably some trapped blood inside the vein that just may take time to heal. If the trapped blood does not resolve, there are ways to successfully remove it.

Veins treated via sclerotherapy become firm, tender, and discolored. This typically lasts a few weeks for small veins and a few months for larger veins. So yes, this is normal.

The lump is trapped blood coagulum, which can be removed a few weeks after sclerotherapy. It will liquefy, becoming easier to remove. Wear compression stockings and walk until then.

Following ultrasound guided sclerotherapy especially for varicose veins the area can become hard due to the vein now becoming clotted with trapped blood from the treatment. Wet warm compresses to the area and ibuprofen will help.

Yes, lumpiness following sclerotherapy is normal. Over time the lumps will be absorbed by your body. It can take up to several months to fully resolve. Warm compresses can help speed up the process.
