I recently asked a question with regards to my treatment, but was thrown off about the answer i got relating to something totally different, i have klippel trenauny syndrome, i've recently had treatment again on my varicose veins, this time i had the foam

Hard to say: I assume you had a foam sclerotherapy injection. Generally in klippel trenauny syndrome, treatments of the superficial veins are limited to those that are really causing problems, as the deep venous system may be underdeveloped and superficial varicosities develop in response to this. The sclerotherapy may not be as effective as for bland varicose veins, but you shouldn't have much pain.

Embolus/lig8/excise: The treatment for kts may involve various combinations of staged resection, ligation or vascular emboluzation to manage symptoms.

Need clarification: As stated before kts can be quite challenging to manage. Please clarify exactly what treatments you have received to date and would better enable answer. If you are concerned about "knots" on your legs following foam scleotherapy these will resolve but may take months and may be improved with draining "trapped" blood.
