every now and then i am getting major coughing fits where my throat closes up and when it finishes i have a vile taste in the back of my throat for 1-2 hours. my rib cage is sore at the bottom and hurts when i move. i'm also getting period pains even though it's not my time of the month. i'm not sure if all of these symptons are tied in together but i'm very worried. please tell me whats wrong. :'(
