Is Incision Pain 3 Weeks After a Breast Augmentation Normal? -25 Days Postop High Profile 300cc Saline Implants? (photo)

my left breast incision has pain & can sting/burn @ times. My surgeon said it was probably the nerve regenerating. when I push myself up to a sitting position in bed, or reach for something, it can throb for hours. surgical glue was used & I had little strips over the incisions until last week. But, it feels like a small piece of plastic thread sticks out from the left one. comparing it to my right one, I raised my breast a bit to see, the right incision pulled open some. Is this normal?!
