In September 2015 I had a heart attack followed by a quadruple bypass. Good recovery and back to normal within 6 months. However in the last few weeks I have noticed pain in my sternum when making certain movements or if I inadvertently roll over onto my front when sleeping - when sleeping the pain is acute enough to wake me. To the best of my knowledge I haven't strained any muscles in that area or had any sharp blows.
Is it possible that one of my sternum clips/wires has moved or 'broken' ? I don't want to bother my GP unnecessarily so thought I'd check to see if anyone else had experienced something similar.
