Hello, You have itching and redness around the area of incision is usually associated with skin vascular conditions such as hemangioma or lymphangioma. Need not to worry. It is not nerve damage rather localized damage. I would suggest you visit a physician once and get the area of damage examined. You should apply Thrombophob gel and ice pack on the site of the swelling. Sclerotherapy and laser therapies are recent treatment options available and the most effective ways of reducing it. Apply numbing gel in the local area as well. It will take two to three weeks to heal it properly. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Harry Maheshwari
