Small Hematoma after breast augmentation? Will it clear up on its own? (photos)

This happens not that infrequently, where one side has an ooze of blood in the post op period. Often times while the surgeon is operating, blood vessels are in spasm and they open up later once the body is awake and relaxed. The trouble with minor post op bleeding like yours is that there is a higher risk for a capsular contracture. You should speak to your surgeon about taking medications to try to prevent the capsular contracture and/or an early massage program. 

Your hematoma looks really small and it will likely resolve on its own.  If you were my patient, I would give you the same advice your surgeon gave you.  Make sure you follow up closely with your surgeon.  If the bruising became worse or your left breast starts enlarging, surgery to remove the hematoma may be indicated.  You may be at increased risk for capsular contracture.  Another reason to stay in close touch your surgeon.  Sometimes an asthma medication can help with an early capsular contracture.  I wish you a smooth recovery!
