I don’t think your problem is related to a breast condition.Pain under your left breast, could be due to several things. For example,Costochondritis, (chest wall inflammation) flatulence,ulcer,angina, pulled muscle,acid reflux, stomach inflammation etc...All these symptoms could very well cause the pain you are describing.
Therefore,,if I were you, I would consult a doctor as soon as possible to diagnose the underlying cause.
I have the same pain- have you received any answers?
"justlynn01" might not see your post in the Forum,but if you wish,you can send her a private message by pointing your cursor on her screen name and then click on message.I hope you get an answer from her,but please note that your condition might not be the same as hers....Many disorders could cause pain under the left breast,so the best thing to do, is to see your Doctor for an evaluation okay?.
