Okay I have been having these sharp pains below my left breast. It feels like a sharp knife stabbing me. It first started happening a long time ago at a football game and than a couple of months ago it happened again but it was a sharp pain after one another for like 30 seconds. Then recently the feeling has been coming up a lot lately. Today I went to DQ with my friends and like every time i laughed i felt a sharp pain in my chest. Than when we got to church as i was walking in it happened like every 5-10 seconds. Can someone please tell me what it might be or something
