Numbness After Fat Transfer

It's been 3 wks post-op after undergoing a full facial fat transfer to manage significant volume loss due to aging. I've been experiencing numbness-like tingling sensation in all the treated areas which is emotionally unsettling. Is this normal & how long does this sensation typically last. I was told my by PS that significant swelling from this type of procedure can persist up to 8 wks however, fully subsides approx 6-8 mos out. I still have chipmunk cheeks & my upper eyelids are also swollen.
