Pain in calf after sclerotherapy. Can anyone advise me what it could be and how long it could take to clear?

I would evaluate this with a clinical exam and diagnostic ultrasound. If there is no blood clot, I would suggest Plato's Omega vein cream and Venasmart compression stockings. Best, Dr. KaramanoukianLos Angeles

Please see your physician to determine what is best for treatment at this time, this could be superficial clots that need expression.  Best, Dr. Emer.

For pain after sclerotherapy, return for venous Duplex scan to exclude DVT and guide treatment for possible superficial vein thrombophlebitis. H Karamanoukian MD FACS

This can all be normal but you definitely need a ultrasound to rule out a deep vein thrombosis.  A 4 cm vein required a large volume of sclerosing agent and cause pain as the vein fibrosis and scars down.  I recommend Ice, compression, elevation and NSAID's for pain.  It should improve over the next coulple of weeks.  

What you need is a venous ultrasound to ensure that there is no DVT which could happen following sclerotherapy of varicose veins.  Most likely you have pain from the treated varicose vein which has now clotted and will improve over time with heat to the area and ibuprofen.  However, a DVT needs to be ruled out.  Follow up with your treating physician.

Hello, there are many reasons for your pain, however the most concernign reason would be a deep venous thrombosis.  All because you're not swelling does not mean that you don't have one.  It's quite worrisome that you are having trouble walking.  For this reason alone, I would certainly recommend obtaining an ultrasound.  Other causes include superificial thrombophlebitis, a known side effect or complication of this procedure which will resolve on its own (quicker with ibuprofen, compression stocking therapy, and heat compresses)

Any unexplained severe pain in the calf should be evaluated to make sure it is not  a blood clot, regardless of whether or not there is swelling.  I recommend you seek immediately medical attention.

by removing the stocking early this may have allowed the vein to fill with clot.  And cause superficial thrombophlebitis.  I would recommend and ultrasound to confirm that nothing more dangerous is going on.  And this is often helped with warm compress and NSAIDs.  In some special cases certain types of blood thinners can help with the pain and prevent propagation.   This usual improves after 10 to 14 days but varies.
