Why do I have pins and needles years after liposuction?

Usually the sensation of pins and needles subside after a year postop. However, there are cases like yours where the sensation lasts for up to 2 years. Chances are your nerves were severely damaged during surgery or you have very sensitive nerves. An in-person examination would be the best option for you as of now. Schedule an appointment with your original surgeon and have a re-evaluation of your condition.

Sorry to hear about your nerve problem, hablapabla.
You didn’t mention how many years have passed since your liposuction, but typically, the pins and needles sensation should have gone away a year after your liposuction.
If it’s been more than a year and you’re still experiencing it, the best thing to do is to go back to your experienced and board-certified plastic surgeon or visit your general physician for a physical evaluation and proper management of your condition.
Best of luck!
