BR 1 year po, feeling large hard lumps/knots in some parts of my left AND right breast. Should I be concerned?

Got a breast reduction on June 9, 2017. healing process was not ideal and did have to go thru a scar revision surgery on my left breast in December 2027, due to a reaction with the stitches and my skin rejecting multiple types of stitches, which caused my incision to separate and open back up. now that the wound has closed, i’ve noticed large lumps in my left breast and some in my right now as well- passed it off as scar tissue but there’s pain upon touch in the left.
