Help!!!! I'm only 14 I've already been to the doctors once but they said it was strep, though the antibiotics have stopped working. The cough is only getting worse I cannot go 30 seconds without hacking. Mucus is really thick, I've been coughing so hard I'm getting cramps in my stomach and ribs. Lungs are beginning to really hurt. sore back & muscles in neck, the itching in my throat wont go away. Very swollen glands&tonsils... Causing lack of sleep & disturbing everyone around me. Very tired constant coughing also causing headaches. I will admit I do smoke though, not that it really has much to do with it. Help???? not that it has much to do with it either, haven't had my period in 2 months?
