Rib pain

Okay ladies. So about 4 weeks ago my left side ribs started hurting. It was mild and tolerable. I got the flu and bronchitis and was coughing like crazy for almost a month. I'm finally over the stuff but now BOTH sides of my ribs are hurting and its so unbearable. When I put pressure on either side (like going to lay down) it hurts so bad. Then when I take pressure off the ribs the pain is so strong it almost takes my breath away. I don't know what to do because it's so painful to lay on either side and we aren't supposed to lay on our backs. Has anyone else experienced this?!?!
