I am a 17 year old girl who has had a nagging cough for 6 months now along with sharp rib and chest pain time to time. I also get sharp back pain as well. Currently every time i breathe in deep now, i start to cough and wheeze. I am also suffering from headaches and fatigue no matter how much i sleep. Other bones in my body are also very weak and ache a lot. Should i see a doctor? What do you think it is?
