What caused my severe bruising? Appears to be the worst implant bruising on the Internet! PS said as long as I didn't have symptoms, fever, hot to the touch or swelling, that im ok. Ribs extremely tender bruising was just horrific! Inspiras implanted under the muscle. I followed Dr's preop inst. Im 4 wks post op and feeling better. I did use Arnica. My PS didn't require a physical or blood work. The bruising appeared around day 4. Why did this happen?
