sharp chest pains and under arm,left breast and left arm pain AGAIN.

AI am having the exact same pains only mine are accompanied very rashy feeling nipples.I am 28 yrs old and have a 2yr old. I have never breastfed. I saw the doctor yesterday . I didnt really get any answers. I was told to take Advil twice a day and not to lift anything heavy. Im very $cared it could be breast cancer. I do not have a history of Cancer in my family but the pain and nipple thing are symptoms of. I have a follow up in 2 weeks. S

Wow I'm been having very similar symptoms for months now but haven't found a lump. When it happens it's like really quick sharp pain in my left breast sometimes in my armpit too. Sometimes i even get pains in my left hand and arm, but it's always on the left and always very localized (no aching just very specific and intense)

It makes me panic SO much when it happens cuz i worry that I'm having a heart attack but I get no other symptoms. it's been happening on and off for about 8 months now.

Has anyone found a cause for this?? It's really upsetting scares me so much sometimes I worry it's breast cancer but I'm only 22 and have no family history of breast cancer or heart issues
