Sharp pains on the left side of chest

I've been having reoccurring sharp pains on the left side of my chest, directly under my left breast, seemingly in my heart. They are sharp stabbing pains that come and go, and last a few seconds to a few minutes. It's bearable, but very uncomfortable. I'm only 31, but heart disease runs in my family, so it's a bit concerning. I don't feel sick in any other way. Are these symptoms that I should be concerned about?

i have had those type of pains for 11mths following a couple of bad chest infections, i suffer with palpitations too. I have had lots of tests on my heart after a trip to the ed. All have come back normal. I suggest to set ur mind at rest and go have some tests, my gp put mine down to costochondritis.
