Dear cherry_pez,
Liposuction can usually be performed with minimal discomfort.
For patients who want smaller amounts of liposuction performed on a limited number of areas and have normal pain tolerance, liposuction can usually be done comfortably using local tumescent anesthesia combined with oral medications. The initial injections of the local and tumescent anesthesia will sting, but the areas injected should be dull and numb afterwards. During the procedure, there may be some sensitive spots, but most patients are able to tolerate this comfortably with minimal to mild discomfort.
For patients who are unusually sensitive to pain, who are very concerned about the possibility of being uncomfortable during the procedure, who have a history of chronic pain, or who desire treatment of multiple large areas during one operation, liposuction is best done under tumescent anesthesia combined with intravenous sedation (twilight sleep) or general anesthesia. When you are under twilight sleep or general anesthesia, you should feel little (if anything) during the procedure. Be certain that the operating room facility is certified by AAAASF, AAAHC, or Medicare so that the highest standards for patient safety and care are met.
After liposuction, most patients experience mild discomfort, which is often described as a deep tissue soreness comparable to an extremely vigorous workout. There may also be sensations of swelling, numbness, stinging, and/or burning. These symptoms are usually controlled with oral pain medications. Having said all this, pain varies among individuals, and "most" does not equal "all." Some patients experience little pain, most experience mild pain, but a few will report higher levels of pain.
The type of anesthesia matters, but the type of liposuction should not have a big impact on the amount of pain experienced. Beware of marketing hype is somebody tells you otherwise.
Warmest wishes,
