I had foam sclerotherapy 4 months ago and I still have a lumpy and sore area. It hurts after sitting for a while. Is this normal?

It was a large vein that was treated and whilst it no longer protrudes, you can feel it under the skin.

Yes, this can be normal. The vein usually shrinks over time.

This is the reason I do not treat larger varicose veins with injections. You may have an area of "trapped blood" which should be drained. This is easy for your doctor to do in the office. Low heat over the area for 10 minutes as often as possible will also help. As a vascular surgeon, I remove large veins through tiny punctures under local anesthetic in the office. This requires no stitches and has no downtime. It is also cosmetically pleasing and causes no trapped blood.

You probably have trapped blood. I recommend you see your surgeon and have it removed. It may go away on its own over a year or two as well, however if it is bothering you, you can certainly have it removed.

What you describe occurs commonly following foam sclerotherapy. The treated vein clots and can get hard or lumpy. Applying wet heat to the area will soften it, and ibuprofen will help. I usually drain (evacuate) this area under local anesthesia by inserting a needle into the hard area which will drain the clot and eradicate the symptoms.

20 years ago I had liquid Sclerotherapy and was bandaged for one month. The veins weregone when removed.Two months after my foam sclerotherapy my veins are still there. I know brown pigmentation takes a while to fade. The only difference is that this time I was only given compression stockings, not tight, to wear for 1 week. I've been wearing my own (stronger) stocking for 7 weeks, but no improvement. I'm very disappointed. Will the veins ever improve?

I am thinking about having foam sclerotherapy and I was once told by a doctor that the blood will clot from the foam and then the foam shrinks the vein. Can you explain this process? How long does the blood clot stay there? Is it a concern, and is there a risk of developing other problems from this treatment, such as cancer?

I had foam scleotherapy 16 days ago on a very superficial varicose vein behind my left knee. The surgeon injected the vein with foam; however, at that moment, I felt pain along the vein in my inner thigh. I had severe bruising along this vein even though it was far from the site of injection. I now still have bruising and there are palpable tender lumps along the length of the vein on my inner thigh for about 4-5 inches. Is this normal? What do I do?
