Hey, Cerys.
I had the exact pain in my right boob.
I noticed that my surgical bra and breast band were too tight on me.
I also realised that I would wake up in the morning, leaning on my right side more which left me in agony getting up.
Once I made these changes it took about 2 days for the pain to stop.
Have you kept up with your pain meds?
I was given Robaxin, a muscle relaxant which helped me loads…
I hope you feel better soon, hun xx
