Incision discomfort 3 months after breast augmentation from working out? (Photo)

Hello, I had BA surgery 3 months ago (silicone 300cc under muscle with incision under the breasts). My dr cleared me to work out after 6 wks (any kind of workouts) and since then I have been working out 6 days/wk. I do upper body weights and planks in addition to lower body, but have noticed my incisions are still very sore and feel bumpy (this has not changed or gotten better). Is it normal for the incisions to still feel sore and painful or could it be from working out? Thanks very much !
