I woke up last night for what felt like a muscular pain at first in my breast, but it would not go when I changed position.
For the last 24 hours, every 10-30 minutes or so I keep getting a sharp pain in my right breast, always in the same place. I've had a good feel and can't feel any lumps or bumps. I occasionally get breast pain in my cycle but this is different and more sharp.
Obviously your brain goes to worse case. Does this sound particularly concerning?
