Is normal to get headache chills after varicose vein treatment?

Thank you for your question.Local anesthesia can cause specific symptoms if the dose is above that recommended per Kg of body weight. I have never seen or read about chills being a side effect of vein treatments such as endovenous ablation, tumescent anesthesia or local anesthesia or sclerotherapy.Contact the treating physician.Dr. Karamanoukian

Your question is a little vague.  There are many kinds of varicose vein treatment such as closure procedures, microphlebectomies and sclerotherapy.  Headaches can occur for many reasons including anxiety and may not be related to the treatment at all.  Chills are uncommon following vein treatment and could be related to the tumescent solution especially if cold.  They also may be unrelated to the treatment.  Follow up with your treating physician.
