Hi - have right armpit pain sometimes radiating to hands and back for 3 weeks.Neck also heavy. Breast ultrasound done on August 18th was Birads 1 for pain in left breast. Shown to breast surgeon a week back who says muscle spasm after a pinch test. But have got no relief post muscle relaxant. Pain increased when I lift my hand over head or put hand behind head while sleeping. Should I ask for another ultrasound or does this seem to be a musoskeletal issue. No swelling or new lumps felt.
