I had five long stents put in my left coronary artery and had a pinching sensation for a few weeks, a bit like the stitch you feel between your ribs when running sometimes, only a lot deeper. I received a call the day after discharge and it was a nurse but it was her opening words which shocked me "you need to drink lots of fluids, and you may feel a kind of pinching in your left side for a while". Was she psychic or what.
