I have severe pain under my right brest for past 3 years. I got multiple breast USG but nothing was found then got a HRCT suggested by my pulmonologist and they detected sternalis muscle which is causing pain in chest and back but they ask me to take painkillers when in severe pain. Painkillers, physiotherapy did not work. Can this sternalis muscle along with this pain cause any problem in the breast in long term . Also can this be removed as this is making me disabled each day.
