Soreness under breast implant scar, 7 months post-op

I had breast augmentation 7 months ago and it’s been relatively easy as far as pain except I get soreness still under my right breast when wearing a bra. It’s now been over a week that it hurts despite not wearing a bra. My right breast was much smaller than my left and has given me the most trouble. Is it normal to still have this pain? I did just see my dr for a follow up but was feeling fine. He said everything looked well. I also have pain the wraps around into my back muscle.
