Fat necrosis? Full body lift 6 months ago: TT w/muscle repair, arms, thighs, breast lift, back lift, and lipo. (Photos)

Had 2 areas in my tummy tuck that had necrotic tissue an required revision. One area above my pubic area and below my belly button. Surgeon had to cut and stitch below my belly button. This area is still hard and discolored, doctor says it's fat necrosis and will eventually absorb. My stomach muscles near my belly button are still sore as well, have checked with the doctor numerous times and he says it's the margins of healing and the fat necrosis. Was wondering if I should be concerned?
