Hard Bruised Lump After Sclerotherapy

Aspiration of a post-sclerotherapy nodule is a very simple process. If the firmness is really bothering you, consider speaking to your physician. Either way, it will resolve with time. 

Sometimes hard tender bruised lumps can be lanced and draied of clotted blood which may decrease the chance of pigmentation. See your doctor for evaluation.

Trapped blood in the varicose vein can get swollen and hard and is easily removed by your doc.  The sooner the better but 1 month is not too late.  If you do sclero enough, you will get this once in a while. 

To be on the conservative side.  warm compress with compression stockings should do the trick.  If there is significant pain and/or swelling I would recommend seeing your treating doctor to determine if more invasive treatment is needed.  This can include draining the "trapped" blood in the treated vein.  

We routinely see patients after sclerotherapy for varicose veins and if there are lumps that are painful, we perform an urgent venous Duplex scan to exclude DVT - which is rare but a known side effect of sclerotherapy.
