Regression and pain 6 months after BBL. What can I do?

I had a BBL/Lipo this past December. I seemed to heal quickly and had no pain in my butt area after 2 months. Around the 4 month I started to experience soreness in my butt and hips. I also seem to experience blood draining from my face whenever I lay down for extended amounts of time. I wake up pale and weak until i take my daily iron supplement. My color returns but it happens again each night. It is hard to sleep because im so sore. My compression garment seems to help relieve the pain though
