Recent fat transfers palpate as hard nodules under facial skin. What's normal? 8 days post op. (photos)

Autologous fat grafts palpate as hard, discrete and nodular. Respected physician assures this is normal. Is this normal? Is it wise/unwise to massage these? Are they less predictable than fillers might have been? 2 "gum balls" where I'd had jowling and pearl-sized bumps under eyes. As edema goes away, lumps look more prominent. I'm in my late 40's, 8 dyas post-facelift , lower lid blepharoplasty w/numerous autologous grafts to face.
