I am also having sharp , quick pains in my chest, on the left side, between my breasts
. Sometimes, I am not doing anything when I get them, other times I feel
them when I bend over. I have also had some pain in my left shoulder. Last night, I was talking on the phone, and I got this sensation in the center of my chest. It felt like a million forceful bubbles were being released. it made my heart beat really fast and lasted for about 15 seconds. It did not hurt.
