Much depends on the size of the liposuction you had and to some extent, how it was done.
Gererally, it takes many months for the body to heal following a liposuction. However, comfort should increase rapidly after the first 10 days. Be aware that there are two standards of care for liposuction: Tumescent liposuction under local anesthesia with microcannulas and liposuction under general anesthesia. Tumescent liposuction under local anesthesia is the type of liposuction practiced by dermatologist and cosmetic surgeons trained by dermatologist.
Because the patient is awake during the entire procedure, the surgeon proceeds at a pace that is comfortable for the patients. There is generally much less trauma associated with this type of liposuction as a result. It is not unusual for patients to be working out two days after liposuction and to be out of compression garments 3 to 5 days after the procedure.
Liposuction under general anesthesia is what is commonly practiced by general plastic surgeons. With a patient fully asleep, there is no awareness of the procedure and the surgeon can more rapidly perform the surgery. Consequently, there is more trauma associated with this style of liposuction. It can be 10 weeks before a patient undergoing this type of liposuction is comfortable enough to resume a work out. Also, it is often necessary to be in compression garments for 6 weeks after such a procedure. Persistent discomfort following this style of liposuction is therefore to be expected.
Again, it is best to contact your plastic surgeon and be seen. Let them assess you and follow their advice. A responsible office will want to follow you closely and address your concerns under these circumstances.
