Hi my name is chloe, I'm 15 years old. For a while now I've had this sudden pains in my ribs. Recently they've got worse, basically; Suddenly while doing normal daily activities I get a fullness/pressure pain in my rib cage area, whist I have this I begin to have difficulty breathing and sometimes get a headache, Nausea, sweating/chills, back pain and dizziness. What might be the the problem that is causing this?
