7 weeks after neck, face and brow lift. Just finished course of antibiotics and still have tenderness and swelling

Its been 7 weeks but my jaw area and just behind my ears going down my neck is still swollen, numb and tender to touch . The antibiotics improved it but I'm worried something is wrong underneath still . Not massively painful but I can't rub that area if i want to wash my face it is like pressing on a bruise ..sort of . I cant lay my face on a pillow even as too tender . What could it be ? Is it normal ? many thanks
