ive had a cough for the past month now and have pretty much left it untreated, its slowly got worse tho as the right side of my body hurts when i cough, which is fairly painful, the other day i coughed and there was a crunch from my side and felt like my side/back had gone. i have been blowing my nose which there seemed to be blood when doing so and coughing some up too a couple of days ago, although has since ceased. also i sometimes go half deaf because of the congestion that i have, is there anything that i can do to releave the symptoms?
