Drainage hole closed yet still have fluid in back after lipo

You should consult with a board-certified plastic surgeon to check your situation. Your description sounds like a seroma that will need to be aspirated are probably several occasions.

I'm sorry to hear about the problems you're having, but it is difficult to address this via this forum.I'd suggest that you contact your surgeon and see if he or she can recommend someone near you; perhaps there is a connection there.  Otherwise, you should make appointments to see one or more surgeons in person.The fluid may be adequately absorbed on its own but it is impossible to say with an online consultation.I hope that this helps and good luck,Dr. Alan EnglerMember of #RealSelf500

Well, it sounds like you may have a "seroma", which represents trapped fluid either from the tumescent anesthesia and/or excess swelling.  It would be wise to see a qualified surgeon to evaluate, and perhaps drain the fluid.  Good luck!
