Squeezing sensation below left breast

When does this sensation occur? What triggers this feeling? Does it happen on and off or only occasionally?

It happens occaisionally. Im wanting to say when Im sitting or maybe when im laying. Just a couple of times a day. Its not intense but noticeable.

From what you're describing, the sensation may be caused by the spleen, pancreas, or kidneys. I think that if it's intense enough, you should go see your family doctor who can help diagnose the cause. Just so that you can get a more visual idea of what is where in your torso, I've attached a diagram of the organs. Check it out and you can really pinpoint possible causes for your pain. But go get a diagnosis!

I've had similar symptoms for years with sharp pain. It's becoming more frequent and intense. Four different doctors dismissed my symptoms/concerns (the last three physicians were at a free clinic--that is, I don't have health insurance).

Thank you. About a month ago I was experiencing heart palpitations. Wore a heart monitor for 24 hours, ekg was fine and blood work came back fine. It lasted about a week with palpitations about every minute. (but not when sleeping). They since then went away. However after they went away the squeezing came. About 2 weeks ago I ate a big lunch and felt stuffed in that same area and had just a couple palpitations right after that. Could something be inflammed there and pushing up against my heart to where palpitations could happen? Not sure if that makes sense. I eat light meals now and have lost a few pounds. I weigh 160lbs now and need to lose about 15 more. I keep questioning wether somehting is pushing there and can cause palpitations.

I'm not sure, really. I'd suggest that you see an internal medicine specialist, though. And keep a diary of your symptoms...so that you can target the possible trigger and provide as much information as possible to the doctors!
