4 days post left breast explant. 615cc silicone. Still in a lot of pain. Why?

4-11-2018 I got my breast augmentation , I had problems with the left breast since day one !! Pain went from bad to worse as the days passed 2 weeks post op I developed 2 holes with drainage , I did everything I could to save my implant even took the excruciating pain 5-10-2018 I had an emergency surgery due to the implant being exposed IM STILL IN THE SAME PAIN BACK PAIN & STABBING PAIN IN THE BREAST WHEN I BREATH OR LAY DOWN . I'm guessing back pain is from me sleeping on my back for a month ?
