Lumpy Thighs After Liposuction?

One week is early after surgery. However, I recommend that you check with your surgeon to rule out any hematomas. In general, I recommend lymphatic massage and compression garment for my patients for 6 weeks.

Thank you for the question! It is rather difficult to fully evaluate your situation without an in-person exam. That being said, small lumps and other contour irregularities are not uncommon after liposuction.  Shortly after surgery, you may see collections of blood (hematomas) or pockets of fat (fat necrosis). Typically, they will resolve in 2-3 weeks along with most bruising. Keep in mind that you may continue to see lumps as a result of swelling. It will take additional 2-3 months to completely subside.  
Although some physicians recommend massaging these lumpy areas, it's effectiveness is not entirely confirmed. I'd suggest that you give it time and let healing process complete naturally. If your swelling persists months after the procedure or you begin to experience increasing discomfort, you should notify your plastic surgeon. 
Remember that an in-person exam with a board-certified plastic surgeon would be the best way to assess your situation and guarantee an individualized medical advice. Best of luck! 

In general, liposuction will make smooth surfaces lumpy and lumpy surfaces more lumpy. But things can worsen or improve post-op depending on individual circumstances. Much of it depends on the anatomy you begin with. Discuss your concerns with your surgeon and see if massage, Endermologie, additional compression garments or other treatment might be beneficial.
