Minimally invasive procedures, may have some side effects, including some slight bruising, which commonly disappear within the first few weeks. With laser treatment, you will feel a delayed tightness (or "pulling" sensation) 4-7 days after treatment which is normal and expected following a successful treatment. All surgical procedures involve some element of risk and have the potential for complications. Potential complications include, but are not limited to, vessel perforation, thrombosis, pulmonary embolism, phlebitis, hematoma, ecchymosis, paresthesia, skin burn and infection. Consult your physician for further information.
