5'4, 130lbs, ticklish stomach after lipo 1 year ago, is it going to go away?

Just know that you're not alone when it comes to unusual sensations after a procedure. Everyone's body responds to surgery, or trauma, differently. In fact, your body can't tell the difference between trauma and (cosmetic) surgery). Often times, nerve regeneration (specifically sensory nerves) can give the feeling of burning, zapping, or an uncomfortable feeling. This feeling, however, typically resolves by 12 months post-surgery, on average. Hope this helps. -Dr. Sean Satey, Beverly Hills, CA.

From your description it sounds like some hyperactive nerves. There are various techniques you can use to calm this area down a bit. Some have improvement with using ice intermittently or tactile desensitization. Hopefully over time you will find some relief.

Problem that you are experiencing is very rare but may happen in any area where significant skin undermining (lifting) is needed like in abdominoplasty (face lift). Due to complex reinnervation proces, some patient may have feeling of hypersensitivity, tickling, for a long time after surgery. Desensitization is something that you can learn to do yourselft if you schedule evaluation and training by a physical, hand therapist. Hope this may help.
