I m a 18 year old female and I have rib pain on my left side. It s been going on for 25hours now. It had spread to my shoulder and the whole left side of my neck also along with the rib pain. Laying and sitting down cause me to lose my breath and make me go into some kind of attack. I have to use my boyfriends inhaler to calm my breathing. I now walk at a slow pace because if I walk normal I lose my breath and get a feeling I m going to pass out. Not sure if this matters but women in my family and past generations has had tumors by their ribs, lungs, and breasts and also every woman in my family is big breasted. My mom recently got out of surgery because of the one by her ribs. I ve always had this pain since I was about 12 years of age but only lasted about 20 minutes tops. Thanks for your time.
