Hi, for the past 2 days i have not been able to cough.i can feel it in my chest but no matter how hard i try to cough it still won't come up. i have t?

Non-productive cough: If you force yourself to cough when nothing comes up, it will cause worse irritation of the airways, so it is better try not to cough. It sounds like the mucous is too thick to come up, so you can try a medicine like guaifenesin to loosen it up and make it easier to get out. If the tickle in your throat is bothering you, try a cough suppressant like dextromethorphan. If fevers, see your doctor.
