<s>[INST] when i work out i can feel isolated soreness across my upper chest, i can also feel a small lump on the inner upper (about 2 inches down from my collerbone)part of my right breast. when you push down hard on the lump it is tender. I do have breast implants, with the right one sagging. [/INST] Hi.Thanks for your query and an elucidate history.The best way to diagnose this is to undergo clinical examination by a Surgeon and to undergo high resolution ultrasonography and if advised FNAC- fine needle aspiration cytology.. All this will lead to a proper diagnosis and give the plan for a perfect treatment. </s>
