I need advice. Complication of sclerotherapy foam leaking into muscle in my calf and great saphenous vein by mistake? (photo)

Following ELA of the short saph vein in my left leg, side veins were treated by USG foam sclerotherapy. U/S, showed the foam had leaked through a vein to the muscle. I was told to take half aspirin daily for 1 month. I have hardening, redness and tenderness in the great saph vein on the same side. My GP, ordered a U/S that showed the foam had leaked into the great saph and muscle. How can this be remedied? Is the specialist at fault? Does this event occur often with these procedures?
