Why do you Itch after Liposuction? How long does the itching last? It's driving me crazy. I had my surgery three months ago.

Following liposuction, the nerves can sometimes be irritated by the action of liposuction itself.  While they are healing, the sensations that are transmitted to the brain can be interpreted as numbness, itchiness or several other sensations.  This is normal.
Nerve tissue is generally very slow to heal and the process of recovery takes longer than for other types of tissue, such as skin.  We have seen clients report itching for a few weeks, although 3 months seems a bit long.  I would consult with your surgeon to see if anything else might be going on.
Hope that helps.
