3 weeks post op Breast Augmentation, I have this sharp pain under one breast. Is this normal?

About 3 weeks post op BA 660cc in the left and 680cc in the right, saline under the muscle. My breast look wonderful, I am very happy. My left breast was swollen more then the right, with more discomfort ( nothing major). Now both breast are very tender,frequent pain under my left breast along the incision. With little pressure it eases up but this happens all day. My breast are symmetric, about the same size now, no signs of infection the incision looks great. Is this normal? When will ease up?
