My Seroma on Lower Back is Getting Larger, Hardening and the Area Has Started Bruising? (photo)

Seek immediate insertion of drainage system of recurrent seroma/hematoma before it becomes infected. 

    Any concerns about hematoma or seroma should be referred to the plastic surgeon and mandates exam with possible drainage.  Kenneth Hughes, MD Los Angeles, CA

You need to visit your plastic surgeon who performed the surgery.  If there is fluid present, the fluid needs to come out, either through needle aspiration or drain placement. Followup is very important to successful results.
