Just Had Orthognathic Surgery, Swelling in Lower Lip is Still Very Bad, When Will That Subside?

3 weeks post op I have no feeling in half my face, and even the top of my face feels a little numb, my lower lip is still huge and swelling doesn't seem to be going down. I also had lipo in chin, neck and there are huge ridges, that are hard feeling and really painful and also not going down..is this normal? The Dr says it is fluid, but I am afraid it might be scarring, is that possible? I am really freaking out. She said to put moist heat and lightly massage, which I try to do, but it hurts!
