Still Have a LOT of Pain Behind my Knees 10 Days Post Op, What Can I Do?

You need immediate evaluation for a embolus. GO to closest ER &/or call your surgeon to be safe. Better safe than sorry. 

You should call your surgeon to alert him to what you're experiencing. If you don't get a response, then go to an Emergency Room for an evaluation to be sure there isn't anything serious happening to you. The space behind your knees shouldn't have been suctioned. If you're having pain there, it should be evaluated.

Pain is not expected behind knees after liposuction or any surgery. Pain behind knee or calf pain after surgery is highly suspicious of DVT (blood clot) and needs to be considered and ruled out. Blood clots can form is the deep veins of the leg, causing a blockage in circulation. This may cause swelling and pain in the calf and lower extremity. Blood clots are more common in the days and weeks after injuries and surgical procedures. It can be a very serious problem and should be treated immediately. I recommend that you contact your surgeon NOW and explain the location of your pain and your symptoms, he may order an ultrasound to find out if you have any blood clot in the lower extremity. If you are unable to contact him NOW, go to the EMERGENCY ROOM and get an Ultrasound examination of your lower extremities. If it is negative, then every thing is great and just wear also a compression stockinet in addition to your garment; but if positive you need to be treated with anticoagulants to prevent further more serious problems. Please DO IT NOW.  This explanation should not be considered as medical advice and is only for information purpose.
