it sounds like you need something to tone down your cough reflex. start with hot tea with honey but if that doesn't help something to thin your mucus secretions and lessen your cough reflex would help. simple tussin dm or it's generic that is something that includes dextromethorphan and guaiefenesin could help you. if that doesn't do anything either talk to the doctor. you might need a stronger cough syrup than you can get over the counter.
i have an exceptionally violent cough. whenever i have a cold or the flu or bronchitis or anything that causes a cough my cough is very very violent. sometimes it will induce my gag reflex and cause me to vomit. after a day or so it usually feels like i have been in a boxing match my chest and ribs are so sore. coughing so long and violently i can't get air sometimes. any possible answer on how to alleviate this would be appreciated.
