Expectation during recovery stage after lower blepharoplasty with fat repositioning? (photos)

You are still early in the healing phase.  The massage you did would not kill the fat.  The fat can initially feel very firm from the swelling but this should improve with time.  Warm compresses should help to speed up the healing.    

As to massage or not, this really is something to discuss directly with your surgeon. Fat repositioned in the lower tear trough region may feel firm initially but often softens up.

no worries! You did not do anything that will adversely affect your results. Areas of hardness combined with areas of fullness and depressions is completely normal during the healing process.  This should all start to settle over the next three months. Hope this helps and best of luck.
